35 x 4 = 140 |

1 x 2 = 2 |
142 |
| 16 |
16 x 4 = 64 |
20 |
20 x 2 = 40 |
104 |
Total number of wheels if all the vehicles are buses
= 36 x 4
= 144
Big difference between the number of wheels between the buses and the bicycles
= 144 - 104
= 40
Small difference between the number of wheels between a bus and a bicycle
= 4 - 2
= 2
Number of bicycles
= 40 ÷ 2
= 20
Answer(s): 20
