1.Ramu & Sangeeta went for biological analysis to a island which is 34km from their place. They travelled in a boat which went at a speed of 2m/s. when they are in half a distance in the boat sangeeta note there are 7 leg & 8 leg octopuses under the water. Ramu counted the total number of legs of octopuses and got 54. Sangeetha instantly said I know how many 7 leged octopuses are there under the water. They both reached the island after 20 min they left . How many seven leged octopuses does sangeetha calculate?
a. 4
b. 5
c. 6
d. 7
ANS: The options provided are wrong. The answer is 2.
7(X)+8(Y)=54 -- X : no of 7 legged octopus. Y: no of 8 legged octopus. Try substituting values of X and you have to get an integer value for Y.
2.In the reading room of a library, there are23 reading spots. Each reading spot consists of a round table with 9 chairs placed around it. There are some readers such that in each occupied reading spot there are different numbers of readers. If in all there are 36 readers, how many reading spots do not have even a single reader?
a. 8
b. None
c. 16
d 15
ANS: d
The posts should have different numbers -- 1+2+3+4+5+6+7+8=36
Therefore 8 Posts are filled, implies 23-8=15 Unfilled. There are 14 spots. Each spot has 8 seats. 28 people seated in all the spots. No similar number people sat in any spot. How many spots left with no people at all.
3.There are 14 spots. Each spot has 8 seats. 28 people seated in all the spots. No similar number people sat in any spot. How many spots left with no people at all.
a. 5
b. 6
c. 7
d. 8
ANS: c (same logic as above question)
4Susan made a block with small cubes of 8 cubic cm volume to make a block 3 small cubes long, 9 small cubes wide and 5 small cubes deep. She realizes that she has used more small cubes than she really needed. She realized that she could have glued a fewer number of cubes together to lock like a block with same dimensions, if it were made hollow. What is the minimum number of cubes that she needs to make the block?
a. 114
b. 135
c. 21
d. 71
ANS: a
Total number of cubes required to make the solid cube = 3*9*5
To make it hollow, we can remove an inner cube, which has 1*7*3 cubes.
So total number of cubes= 3*9*5-1*7*3=114
5.In the year 2002, Britain was reported to have had 4.3m closed – circuit television (CCTV)
cameras – one for every 14 people in the country . This scrutiny is supposed to deter and detect crime. In one criminal case, the police interrogates two suspects . The ratio between the ages of the two suspects is 6:5 and the sum of their ages is 6:5 and the sum of their ages is 55 years. After how many years will the ratio be 8:7.?
a. 11
b. 6
c. 10
d. 5
6.Francois Pachet , a researcher at Sony Computer Science laboratories is also a jazz musician. He decided to build a robot able to improvise like a pro. Named Continuator, the robot can duet with a live musician in real- time. It listens to a musical phrase and then computes a complementary phrase with the same playing style. If the cost of making the robot is divided between materials , labour and overheads in the ratio of 4:6:2.If the materials cost $108. the cost of the robot is
a. $270
b. $324
c. $216
d. $ 648
ANS: b.
4 is 1/3rd of 12(4+6+2). So you have the answer as 108*3.

Mobile Number Portability:important things you need to know about MNP
The much-awaited Mobile Number Portability (MNP) was launched at Newdelhi on Jan 20.The MNP(Mobile Number Portability) will allow users to switch mobile service providers without changing their numbers.Addressing a press conference Telecom Minister Kapil Sibal said, "It is a historic moment, we have demonstrated that the customer is king. The whole process will not take more than seven days and cost Rs. 19 only which is likely to be reduced further."
Important features of MNP
1)Type 'port' space 'mobilenumber' to 1900 from your mobile eg:port 09564234589 to 1900
2)Then you will receive an eight-digit alphanumeric code and an expiry date for that code from you existing service provide called Unique Porting Code, or UPC.
3)Now you need to contact your new service provider with this Unique Porting Code (UPC), your mobile number and documents for address proof, identity proof, photograph (and other documents as required). Do this before the expiry date and time of the UPC.
4)Now your new service provider will take your request to the mobile portability clearing house which will ensure that you number gets deactivated from the existing provider and gets activated with the new provider. For this to happen your existing provider will have to give approval to the new provider / clearing house. Approval will be given if there are no dues pending with the existing service provider.
5) Once everything is clear, you will get an SMS from new service provider with the date and time of the number porting.
6)When the actual porting happens, your mobile will be in a no-service period which will be of couple of hours (your phone will be dead in these no-service hours). As per mandate these no-service hours will be from 12 AM (midnight) to 5 am. Also it is mandated that one you get a SMS from the new service provider, your number should be ported within 4 days. You will have to use your new SIM from your new service provider after the no-service hours.
7)Subscriber will be charged RS 19 for this process

Important features of MNP
- Number can be ported from one service provider to another.
- This can be done for both post-paid and pre-paid services and for post-paid number portability, there should not be any dues pending with the old operator.
- This will also be available for SIM cards being used for Internet data connection.
- For pre-paid number portability, carry forward of balance from the old provider to the new provider is not permitted.
- When you port your number, you will have to submit your documents (identity proof, address proof, photographs and other documents as required) to your new service provider.
- You will get a new SIM from the new service provider.
- Entire porting process can take anywhere from 24 hours to 7 working days.
- After porting your number to the new service provider, you must stay with that provider for a minimum of 3 months.
- You will be charged Rs. 19 from the new service provider for this which is likely to reduce further.

25.A hollow cube of size 5 cm is taken, with a thickness of 1 cm. It is made of smaller cubes of size 1 cm. If 4 faces of the outer surface of the cube are painted, totally how many faces of the smaller cubes remain unpainted?
800
500
488
900
ans:side of cube = 5 cm
its thichness = 1 cm
so volume of outer cube = 5*5*5
volume of inner cube = 3*3*3
volume of the hollow cube = 5*5*5 - 3*3*3 = 98
so total no of small cubes of the size 1 cm = 98/1*1*1 = 98
we know a cube has 6 faces so total no of face = 98*6 = 588
one surface of outer cube contains a total of 25 surface of smaller cube , so when 4 surface of outer cube is painted total no of surface of small cubes i.e supposed to be painted is 4*25 = 100
so the total no of surfaces of small cube that will be remained unpainted is 588-100 = 488

29.. A lady has fine gloves and hats in her closet- 18 blue, 32 red, and 25 yellow. The lights are out and it is totally dark. In spite of the darkness, she can make out the difference between a hat and a glove. She takes out an item out of the closet only if she is sure that if it is a glove. How many gloves must she take out to make sure she has a pair of each color?
a)50 b)8 c)60 d)42
ans:60
There can be lots of logic for this, but approach the simplest one so that we approach to one of the solutions. Suppose the lady first picks 32 Red gloves, and then 24 Yellow gloves. The next pair she pics will be one Yellow and One Blue which does not make a pair. The next two will be blue gloves. So she make a total of 32+24+1+1+2 = 60 picks.

37.Alice and Bob play the following coins-on-a-stack game. 20 coins are stacked one above the other. One of them is a special (gold) coin and the rest are ordinary coins. The goal is to bring the gold coin to the top by repeatedly moving the topmost coin to another position in the stack.
Alice starts and the players take turns. A turn consists of moving the coin on the top to a position i below the top coin (0 = i = 20). We will call this an i-move (thus a 0-move implies doing nothing). The proviso is that an i-move cannot be repeated; for example once a player makes a 2-move, on subsequent turns neither player can make a 2-move. If the gold coin happens to be on top when it's a player's turn then the player wins the game. Initially, the gold coinis the third coin from the top. Then
a) In order to win, Alice's first move should be a 1-move.
b) In order to win, Alice's first move should be a 0-move.
c) In order to win, Alice's first move can be a 0-move or a 1-move.
d) Alice has no winning strategy.
Consider the situation of a 1-move
---C---
---C---
---G---
C represents the normal coin and G the gold coin. So Alice makes a 1-move, which does not have any effect on the arrangement. Next Bob has to make a 0-move or 2-move. If he makes a 0-move, there is no change and if he make a 2-move, the G goes up by one step. If Bob makes a 2-move, then Alice can do a 0-move and win the game.
38.36 people {a1, a2, ..., a36} meet and shake hands in a circular fashion. In other words, there are totally 36 handshakes involving the pairs, {a1, a2}, {a2, a3}, ..., {a35, a36}, {a36, a1}. Then size of the smallest set of people such that the rest have shaken hands with at least one person in the set is
a)12
b)11
c)13
d)18
ans:a
Understand the question, we have to find the minimum set, so that all other people shake hand to the selected set of people. Let me take an example of 6 people. {a1,a2,a3,a4,a5,a6} Now if we include a minimum set {a2,a5} all other people are shaking hands with them. So if its 2 for 6(1/3rd) then its 36/3=12

After shooting the bear, he drags it one mile due north back to his cabin where he started that morning. What color is the bear?
a]Brown
b]Black
c]Grey
d]White
Ans::
From North Pole, there are an infinite number of points about 1 mile away , where you can walk 1 mile south, walk one mile east (all the way around the earth back to the same spot), and then back north again,
This is only possible if the cabin of man is at North Pole.
He can walk one mile due south, then one mile due east and finally one mile due north where he finds his cabin again. This means that his cabin can only be at the north pole, and for that reason the bear will be white.

29.. A lady has fine gloves and hats in her closet- 18 blue, 32 red, and 25 yellow. The lights are out and it is totally dark. In spite of the darkness, she can make out the difference between a hat and a glove. She takes out an item out of the closet only if she is sure that if it is a glove. How many gloves must she take out to make sure she has a pair of each color?
a)50 b)8 c)60 d)42
ans:60
There can be lots of logic for this, but approach the simplest one so that we approach to one of the solutions. Suppose the lady first picks 32 Red gloves, and then 24 Yellow gloves. The next pair she pics will be one Yellow and One Blue which does not make a pair. The next two will be blue gloves. So she make a total of 32+24+1+1+2 = 60 picks.

37.Alice and Bob play the following coins-on-a-stack game. 20 coins are stacked one above the other. One of them is a special (gold) coin and the rest are ordinary coins. The goal is to bring the gold coin to the top by repeatedly moving the topmost coin to another position in the stack.
Alice starts and the players take turns. A turn consists of moving the coin on the top to a position i below the top coin (0 = i = 20). We will call this an i-move (thus a 0-move implies doing nothing). The proviso is that an i-move cannot be repeated; for example once a player makes a 2-move, on subsequent turns neither player can make a 2-move. If the gold coin happens to be on top when it's a player's turn then the player wins the game. Initially, the gold coinis the third coin from the top. Then
a) In order to win, Alice's first move should be a 1-move.
b) In order to win, Alice's first move should be a 0-move.
c) In order to win, Alice's first move can be a 0-move or a 1-move.
d) Alice has no winning strategy.
Consider the situation of a 1-move
---C---
---C---
---G---
C represents the normal coin and G the gold coin. So Alice makes a 1-move, which does not have any effect on the arrangement. Next Bob has to make a 0-move or 2-move. If he makes a 0-move, there is no change and if he make a 2-move, the G goes up by one step. If Bob makes a 2-move, then Alice can do a 0-move and win the game.
38.36 people {a1, a2, ..., a36} meet and shake hands in a circular fashion. In other words, there are totally 36 handshakes involving the pairs, {a1, a2}, {a2, a3}, ..., {a35, a36}, {a36, a1}. Then size of the smallest set of people such that the rest have shaken hands with at least one person in the set is
a)12
b)11
c)13
d)18
ans:a
Understand the question, we have to find the minimum set, so that all other people shake hand to the selected set of people. Let me take an example of 6 people. {a1,a2,a3,a4,a5,a6} Now if we include a minimum set {a2,a5} all other people are shaking hands with them. So if its 2 for 6(1/3rd) then its 36/3=12

58.A hunter leaves his cabin early in the morning and walks one mile due south. Here he sees a bear and starts chasing it for one mile due east before he is able to shoot the bear. After shooting the bear, he drags it one mile due north back to his cabin where he started that morning. What color is the bear?
a]Brown
b]Black
c]Grey
d]White
Ans::
From North Pole, there are an infinite number of points about 1 mile away , where you can walk 1 mile south, walk one mile east (all the way around the earth back to the same spot), and then back north again,
This is only possible if the cabin of man is at North Pole.
He can walk one mile due south, then one mile due east and finally one mile due north where he finds his cabin again. This means that his cabin can only be at the north pole, and for that reason the bear will be white.

Seminar on Body Area Network Abstract
A Wireless Body Area Network consists of a set of mobile and compact intercommunicating sensors, either wearable or implanted into the human body which monitor vital body parameters and movements such as heart rate,blood pressure,temperature etc. These devices, communicating through wireless technologies, transmit data from the body to a home base station, from where the data can be forwarded to a hospital, clinic or elsewhere in real time over a local areanetwork (LAN), wide area network (WAN),cellular network.So physicians can access this data and recommend the necessary actions.WBAN is still in its primitive stage and is being widely researched.Burgeoning healthcare needs are exerting enormous strain on the fragile healthcare deliverysystem.Shortage of skilled staff,overload, and tightening of healthcare budgets have aggravated the impending healthcare crisis. These economical, social, and demographictrends highlight the need to exploit technological breakthroughs to bring affordable and efficient healthcare solutions to people that will improve their quality of life. The technology expected to be a breakthrough invention in healthcare, leading to concepts like telemedicine and mHealth becoming real.In short Body Area Network is a system of devices in close proximity to a persons body that cooperate for the benefit of the user.
Recent advances in the domain of personal gadgets, sensing and monitoring technology for in-body and near-body use, miniaturization, and energy-efficient wireless and sensor networks have recently come together under the rubric of Wireless Body Area Networks (WBAN). Body Area Networks, as the name suggests, is a network of computing entities around a person that is used to provide important services. WBANs can be utilized in diverse applications such as physiological and medical monitoring, human computer interaction, education and entertainment. Examples include heart-rate monitors, glucose-monitors, accelerometers, medical implants and so on. WBAN is consists of several small devices close to, attached to or implanted into the human body. These devices communicate by means of a wireless network. WBAN topology comprises many transmit only sensor nodes, that have to be very simple, low cost and extremely energy efficient, some transceiver nodes, that afford a somewhat higher complexity to sense and act and few high capability nodes, e.g. master nodes with high computational capabilities and support for higher data rates. The gathered datacan be forwarded in real time to a hospital,clinic, or central repository over a local area network (LAN), wide area network WAN),cellular network, and the like. Physicians and caregivers can remotely access this data
