One day on reaching school I found there were a total of 16 bicycles and tricycles parked in the school compound. I counted the total number of wheels to be 38. Find out the number of bicycles.
10 bicycles.
Explanation:: All the cycles will have at least 2 wheels, so 16 cycles will have 16x2=32 wheels. But in total there are 38 wheels. So the extra wheels (38-32=6) must be of the tricycles because bicycles have 2 wheels and tricycles have 3 wheels.
Therefore, the number of tricycles parked is 6 and hence the number of bicycles is 10.

I have four sides. Anyone can calculate my area if they come to know the length of any one side of mine. I have four right angles within me. Which shape am I?
The captain of a ship was telling this interesting story: "We traveled the sea far and wide. At one time, two of my sailors were standing on opposite sides of the ship. One was looking west and the other one east. And at the same time, they could see each other clearly."
How can that be possible?
The marines were standing back against the sides of the ship so they were looking at each other. It does not matter where the ship is (of course it does not apply to the North and South Pole).
