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.

Name four days of the week starting with the alphabet "T".
Mr. & Mrs. Smith went for a picnic. Mrs. Smith has 5 sons and each son has a sister who has 5 daughters each of whom have 1 brother each. How many of them went for the picnic?
There are a few trees in a garden. On one of them, a pear tree, there are pears (quite logical). But after a strong wind blew, there were neither pears on the tree nor on the ground.
How come?
At first, there were 2 pears on the tree. After the wind blew, one pear fell on the ground. So there where no pears on the tree and there were no pears on the ground.
