Last weekend, I went to play in the nearby park. It was real fun! I rode my new bicycle that Mom had gifted me on my birthday.

On reaching the park, I saw that there were a total of 15 bicycles and tricycles. If the total number of wheels was 40, how many tricycles were there?

Answer: 10

Solution:

Assuming 2 wheels for each cycle, 15 cycles will have 30 wheels. But, there are 40 − 30 = 10 extra wheels.

As bicycles have 2 wheels and tricycles have 3 wheels, there is 1 extra wheel per tricycle in the park. Thus, the 10 extra wheels belong to 10 tricycles.
