48 x 4 = 192 |

1 x 2 = 2 |
194 |
| 42 |
42 x 4 = 168 |
7 |
7 x 2 = 14 |
182 |
Total number of wheels if all the vehicles are buses
= 49 x 4
= 196
Big difference between the number of wheels between the buses and the motorbikes
= 196 - 182
= 14
Small difference between the number of wheels between a bus and a motorbike
= 4 - 2
= 2
Number of motorbikes
= 14 ÷ 2
= 7
Answer(s): 7
