There were some motorcycles, cars and vans.
23 of the total vehicles were motorcycles and cars. There were 6 vans and thrice as many motorcycles as cars. How many more motorcycles than cars were there?
| Motorcycles |
Cars |
Vans |
| 2x2 |
1x2 |
| 3x1 |
1x1 |
|
| 3 u |
1 u |
2 u |
The total number of motorcycles and cars is repeated. Make the total number of motorcycles and cars the same. LCM of 2 and 4 is 4.
Number of vans = 2 u
2 u = 6
1 u = 6 ÷ 2 = 3
Number of more motorcycles than cars
= 3 u - 1 u
= 2 u
= 2 x 3
= 6
Answer(s): 6
