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?

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

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)

5:-Can you make 120 with 5 zeros?

5:-Can you make 120 with 5 zeros?

The questions are tough.

for the fifth one i think i got the answer :๐

=>(1+1+1+1+1)! (since0!=1)

=>5!=120

am i correct :?:

for the fifth one i think i got the answer :๐

**(0!+0!+0!+0!+0!)!**=>(1+1+1+1+1)! (since0!=1)

=>5!=120

am i correct :?:

Yes you are correct

Even i also don't know answer of 4th question

keep trying otherwise i will tell you answer of remaining questions

1:-You are a landscape designer and your boss asked you to design a landscape such that you should place 4 trees equidistance from each other?Tell me How?

K: Place one tree on the top of hill and others in an equilateral triangle on the slope of the hill.

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. ๐

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

K: By using the thermometer as a scale ๐

4:-How would you catch and receive a ball in same direction? (Dropping is from north

K: I don't understand this question. ๐

5:-Can you make 120 with 5 zeros?

K: cos 0 = 1 ๐ (wink!)

yes biggie you are right for 1st and 2nd question only

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?

by melting them and casting them as one we can extend the burning time more right ๐

or do you want to make them burn to 90 min each :roll:

can you please be more specific.... :-o

or do you want to make them burn to 90 min each :roll:

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

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

Ignite second candle after 30 minutes from first candle ignition.goyal420Each 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

Yeah you are right..VegaIgnite second candle after 30 minutes from first candle ignition.

Let us make it some more difficult .if i say 45 minutes๐

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 answer๐ratikagoelFirst 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

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.

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 right๐rajivtiwari4th ques

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

we have two candles have to burn completely in 90 minutes

we will start second candle after 30 minutes of the first candle

we will start second candle after 30 minutes of the first candle

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

and second one will out half now

lit the second end of the second candle it will take 15 minute to completely burnt

lets see after 30 minutes the the first one will completely burnt out

and second one will out half now

lit the second end of the second candle it will take 15 minute to completely burnt

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?goyal420One 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?

Please read the posts before it's answer is already given

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".

-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?

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. ๐

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.
