In a car park, there are 48 convertibles and scooters. If there are 150 wheels altogether, how many scooters are there?
Number of convertibles |
Wheels of convertibles |
Number of scooters |
Wheels of scooters |
Total wheels |
48 |
48 x 4 = 192 |

0 |
192 |
47 |
47 x 4 = 188 |
1 |
1 x 2 = 2 |
190 |
27 |
27 x 4 = 108 |
21 |
21 x 2 = 42 |
150 |
Total number of wheels if all the vehicles are convertibles
= 48 x 4
= 192
Big difference between the number of wheels between the convertibles and the scooters
= 192 - 150
= 42
Small difference between the number of wheels between a convertible and a scooter
= 4 - 2
= 2
Number of scooters
= 42 ÷ 2
= 21
Answer(s): 21
