How Many Cycles? This is another mathematical statement problem which can be solved using logic and arithmetic. Last weekend, Jack went to play in the park near his house. He rode the new bicycle gifted by his grandma on his birthday. After reaching the park, Jack saw that there were 14 tricycles and bicycles. If there were totally 38 wheels, how many tricycles were there in the park?

Answer:
10
Explanation:
There were 10 Tricycles. There were 14 cycles in all, and all of them have at least 2 wheels. So, 14 x 2 = 28. Now there are 38 wheels totally, which means 38 – 28 = 10. So, this means there are 10 cycles with one extra wheel each, meaning 10 tricycles in all.

Let no. of bicycles(having two wheels) be α
Let no. of tricycles(having three wheels) be β
2α+3β=38 [1]
α+β=14(multiplying with 2)
2α+2β=28 [2]
Subtracting 2 from 1 gives us
β=10 ANSWER
