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 13 bicycles and tricycles. If the total number of wheels was 35, how many tricycles were there?
Answer
9
Solution: Assuming 2 wheels for each cycle, 13 cycles will have 26 wheels. But, there are 35 − 26 = 9 extra wheels. As bicycles have 2 wheels and tricycles have 3 wheels, there is 1 extra wheel per tricycle in the park. Thus, the 9 extra wheels belong to 9 tricycles.
