41 x 4 = 164 |

1 x 2 = 2 |
166 |
| 15 |
15 x 4 = 60 |
27 |
27 x 2 = 54 |
114 |
Total number of wheels if all the vehicles are buses
= 42 x 4
= 168
Big difference between the number of wheels between the buses and the bicycles
= 168 - 114
= 54
Small difference between the number of wheels between a bus and a bicycle
= 4 - 2
= 2
Number of bicycles
= 54 ÷ 2
= 27
Answer(s): 27
