self Maths Puzzle

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 30, how many tricycles were there?

Read Solution (Total 1)

Bicycle = 9 ; Tricycle = 4

So,
Bicycle = 9*2 = 18wheels
Tricycle = 4*3 = 12wheels
Total wheels = 18+12 = 30wheels
Total Vechiles= 9+4 = 13 vechiles,
Proved. Solved all conditions..
