1. How can u measure a room height using a thermometer?

Ans: temp varies with height. but its dependent on various other factors like

humidity, wind etc.

 

2. What is the height of room if after entering the room with a watch ur head

strikes a hanging bulb?

Ans: Oscillate the hanging bulb. Calculate the time period for one complete

oscillation by Simple Harmonic Motion (SHM) of the handing bulb. Put it in the

formula T=2 * 3.14 * (L/G)^1/2

L will be the length of the hanging thread.

Add the L with ur height to get the height of the room.

OR

Ans: Drop it from the room and find the time at which it strikes the floor. Using

physics formula s = (at^2)/2 (IM NOT SURE ABOUT THIS ONE)

 

3. Color of bear…. if it falls from 1m height in 1s.

Ans: We get ‘g’ perfect 10 which is only in poles…hence polar bear…color White

 

4. How will you measure height of building when you are at the top of the building?

And if you have stone with you.

Ans: Drop the stone and find the time taken for the stone to reach the ground. find

height using the formula

s = a + gt ( s = height, a= initial velocity=0, g=9.8m/s, t = time taken)

 

5. How wud u catch and receive a ball in same direction? (Dropping is from north

And receiving from bottom not accepted, as it is 2 directions)

Ans: #

 

6. 25 statements given. Some tell truth, some false and some alternators. Find out

the true statements.

Ans: #

 

7. Can u make 120 with 5 zeros?

Ans: Factorial (factorial (0)+factorial (0)+factorial (0)+factorial (0)+factorial (0)) =

120

 

8.There are three people A, B, C. Liars are of same type and Truth speaking people

are of same type. Find out who is speaking truth and who is speaking false from the

following statements:

a) A says: B is a liar.

b) B says: A and C are of same type.

Ans: lets assume A is speaking truth. It means B is a liar then it means A and C are

not of same type.

 

9.5 swimmers A, B, C, E, F and many conditions of their positions like there are

Two b/w A & F, B doesn’t win etc the question was to find who was b/w like E & D?

Ans: #

 

10. in a race u drove 1st lap with 40kmph and in the second lap at what speed u

must drive so that ur average speed must be 80kmph.

Ans: its impossible! if u drove the first lap in 40 kmph, its impossible that the

average speed of both the laps is 80kmph.

for eg. consider one lap distance = 80km.

time req. to cover 1 lap = 80km/40kmph = 2 hrs.

if the avg. speed is 80kmph, then the total time would have taken =

160kms/80kmph = 2 hrs.

same is the case with any other distance u consider. so the avg to be 80kmph is

impossible
