0 |
152 |
37 |
37 x 4 = 148 |
1 |
1 x 2 = 2 |
150 |
13 |
13 x 4 = 52 |
25 |
25 x 2 = 50 |
102 |
Total number of wheels if all the vehicles are sports cars
= 38 x 4
= 152
Big difference between the number of wheels between the sports cars and the motorcycles
= 152 - 102
= 50
Small difference between the number of wheels between a sports car and a motorcycle
= 4 - 2
= 2
Number of motorcycles
= 50 ÷ 2
= 25
Answer(s): 25
