In a car park, there are 33 vans and motorcycles. If there are 120 wheels altogether, how many motorcycles are there?
Number of vans |
Wheels of vans |
Number of motorcycles |
Wheels of motorcycles |
Total wheels |
33 |
33 x 4 = 132 |
0 |
0 |
132 |
32 |
32 x 4 = 128 |
1 |
1 x 2 = 2 |
130 |
27 |
27 x 4 = 108 |
6 |
6 x 2 = 12 |
120 |
Total number of wheels if all the vehicles are vans
= 33 x 4
= 132
Big difference between the number of wheels between the vans and the motorcycles
= 132 - 120
= 12
Small difference between the number of wheels between a van and a motorcycle
= 4 - 2
= 2
Number of motorcycles
= 12 ÷ 2
= 6
Answer(s): 6
