@CIVILPRINCESS • 15 Jan, 2010 The questions are tough.

for the fifth one i think i got the answer :😁

(0!+0!+0!+0!+0!)!
=>(1+1+1+1+1)! (since0!=1)
=>5!=120

am i correct :?:
@Manish Goyal • 16 Jan, 2010 Yes you are correct
Even i also don't know answer of 4th question

2:-If one tyre of a car suddenly gets stolen and after sometime you find the tyre without the screws how will u make ur journey complete?

K: Each tyre can have three screws each. 😉

3:-How can you measure a room height using a thermometer?

K: By using the thermometer as a scale 😐

4:-How would you catch and receive a ball in same direction? (Dropping is from north
and receiving from bottom not accepted, as it is 2 directions)

K: I don't understand this question. 😕

5:-Can you make 120 with 5 zeros?

K: cos 0 = 1 😉 (wink!)
@Manish Goyal • 16 Jan, 2010 yes biggie you are right for 1st and 2nd question only
@Manish Goyal • 16 Jan, 2010 One more question to add you have two candles each will burn for 1 hour individually ie one candle will take 1 hour to burn completely.Now if you are asked to burn both of these candle for 90 minutes ie both candles must burn in 90 minutes?Can you explain me how?
@cooltwins • 16 Jan, 2010 by melting them and casting them as one we can extend the burning time more right 😐
or do you want to make them burn to 90 min each :roll:

can you please be more specific.... :-o
@Manish Goyal • 16 Jan, 2010 Each candle take 1 hour to complete

My question is to burn both candles in such a way that both will take 90 minutes collectively

ie total time should be 90 minutes to burn both

First light up the two ends of the 1st candle and one end of the 2nd candle.

When the 1st candle will burn out ,then light up the other end of the 2nd candle too

Correct answer😀
@ratikagoel • 18 Jan, 2010 4th ques:

If you throw a ball to the any direction ,due to heavy air in opposite direction it return to your place and u can able to catch the ball by not moving from your original place.
@rajivtiwari • 18 Jan, 2010 4th ques

Throw the ball on the wall
it will rebound and u can catch it standing at your own place in the very same direction

Quite satisfactory answer ..actually i also don't know it's answer but i think you are right😀
@rajivtiwari • 18 Jan, 2010 Okay it was kind of easy for me
I heard similar question few years back which i quite correctly remember
Although i don't know it was really a aptitude question or my cousin fooling around
The question was
Everyone was showed the window of the room.
and asked to jump from the window

None of them went ahead
but a guy climbed on the window pane
and jumped back in the room
and he was selected
So applied kind of same logic
@Manish Goyal • 18 Jan, 2010

Yeah i know about this question it was asked in NDA interview once.one of my friend had given this interview but Alas!he was not selected
@sherya mathur • 19 Feb, 2010 we have two candles have to burn completely in 90 minutes
we will start second candle after 30 minutes of the first candle
@sherya mathur • 19 Feb, 2010 for 45 minutes start burning the one candle from both ends and at the same time start burning second one from the one end
lets see after 30 minutes the the first one will completely burnt out

One more question to add you have two candles each will burn for 1 hour individually ie one candle will take 1 hour to burn completely.Now if you are asked to burn both of these candle for 90 minutes ie both candles must burn in 90 minutes?Can you explain me how?
ans: v have to burn the first candle for half an hr. after that v can burn the second candle. so, at one hr both the candles ll be burned. am i correct?

@Manish Goyal • 20 Feb, 2010 Please read the posts before it's answer is already given
@naga lakshmi • 08 Jan, 2012 1) Place thermometer perpendicular to the floor and against the wall.
2) Make a mark on the wall at the top of the thermometer.
3) Shift thermometer up so bottom is at mark.
4) Repeat 2) and 3) until close to the ceiling.
5) Shift thermometer up until it touches ceiling and mark location of highest mark on thermometer to determine fraction of thermometer length for last segment.

This would give the height of the room in units of "thermometers". This is not a standard unit of measurement, but it is a measurement. If you desire a more standard unit like centimeters, then measure the length of the thermometer and multiply by height of the room in "thermometers".
@Nidhi Shetty • 12 Mar, 2014 -How would you catch and receive a ball in same direction? (Dropping is from north
and receiving from bottom not accepted, as it is 2 directions)

isnt it the same? catching a ball or receiving a ball?
@Anunay Sinha • 23 Mar, 2014 • 1 like he meant throwing and recieving the ball.

and i think the simplest way is to use the ball in pendulum, push it in any direction, wait for it to reach the extreme position in opposite direction, then recieve it in between. 😁
@Nikhitha Pitla • 22 Oct, 2018

There are 3 people A,B,C. Liars are of same type and truth speaking are of same type. Find out who is speaking truth and who is speaking false when they say:

A says, B is liar.

B says, A and C are of same type.
