Two sentries were on duty outside a barracks.
One faced up the road to watch for anyone approaching from the North.
The other looked down the road to see if anyone was approached from the South.
Suddenly one of them said to the other, "Why are you smiling?"
How did he know that his companion was smiling?
Although the guards were looking in opposite directions, they were not back to back. They were facing each other.
Tarun Asthnaiya go to his office by local train. However nearby train station is quite far from his place and he used to drive his bike to train station daily with an average speed of 60km/hr. One day at halfway point he relized that due to heavy traffic he got late having average speed of just 30km/hr. How fast he must drive for the rest of the way to catch my local train?
The train is just about to leave the station and there is no way Tarun will be able to catch it this time.

If I were in Hawaii and dropped a bowling ball in a bucket of water which is 45 degrees F, and dropped another ball of the same weight, mass, and size in a bucket at 30 degrees F, them at the same time, which ball would hit the bottom of the bucket first?
Same question, but the location is in Canada?
Both questions, same answer: the ball in the bucket of 45 degree F water hits the bottom of the bucket last.
Did you think that the water in the 30 degree F bucket is frozen?
Think again.
The question said nothing about that bucket having anything in it.
Therefore, there is no water (or ice) to slow the ball down...

A frog is at the bottom of a well. It is a 30 foot climb to get out. Each morning, the frog jumps 3 feet up the path out, but each night, as it sleeps, it slips back 2 feet down.
Thus, at the beginning of the first day, the frog has 30 feet to go, at the beginning of the second day it has 29 feet to go, and so on.
How many days does it take the frog to get out of the well?
It takes 28 days for the frog to get out (it gets out on the morning of the 28th day).
This is because on the beginning of the 28th day, the frog has 3 feet left to travel. Because the frog jumps 3 feet forward each morning, it will jump out of the well on this day.
A petshop owner had a parrot with a sign on its cage that said "Parrot repeats everything it hears". Davey bought the parrot and for two weeks he spoke to it and it didn't say a word. He returned the parrot but the shopkeeper said he never lied about the parrot.
How can this be?
There are three houses. One is red, one is blue, and one is white. If the red house is to the left of the house in the middle, and the blue house is to the right to the house in the middle, where is the white house?
