196 |
| 48 |
48 x 4 = 192 |

1 x 2 = 2 |
194 |
| 45 |
45 x 4 = 180 |
4 |
4 x 2 = 8 |
188 |
Total number of wheels if all the vehicles are convertibles
= 49 x 4
= 196
Big difference between the number of wheels between the convertibles and the motorcycles
= 196 - 188
= 8
Small difference between the number of wheels between a convertible and a motorcycle
= 4 - 2
= 2
Number of motorcycles
= 8 ÷ 2
= 4
Answer(s): 4
