Last weekend, I went to play in the nearby park. It was real fun! I rode my new bicycle that Mom had given to me on my birthday. On reaching the park, I saw that there were a total of 16 bicycles and tricycles. If the total number of wheels was 39 , how many tricycles were there?

The correct answer is option [E] Solution: Assuming 2 wheels for each cycle, 16 cycles will have 32 wheels. But, there
are 39 - 32 = 7 extra wheels. As bicycles have 2 wheels and tricycles have 3 wheels, there is 1 extra wheel per tricycle
in the park. Thus, the 7 extra wheels belong to 7 tricycles.
