40 x 4 = 160 |

1 x 2 = 2 |
162 |
| 27 |
27 x 4 = 108 |
14 |
14 x 2 = 28 |
136 |
Total number of wheels if all the vehicles are cars
= 41 x 4
= 164
Big difference between the number of wheels between the cars and the motorcycles
= 164 - 136
= 28
Small difference between the number of wheels between a car and a motorcycle
= 4 - 2
= 2
Number of motorcycles
= 28 ÷ 2
= 14
Answer(s): 14
