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.

Only one color, but not one size,
Stuck at the bottom, yet easily flies,
Present in sun, but not in rain,
Doing no harm, and feeling no pain.
What am I?
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.

I can fill up an entire room and still not take up any space. Who am I?
As a whole, I am both safe and secure. Behead me, and I become a place of meeting. Behead me again, and I am the partner of ready. Restore me, and I become the domain of beasts.

1, just one! It is the day when we hit the earth. It is a different story that we celebrate our birthday every year, which actually implies Anniversary.
