There were some cars, vans and lorries.
58 of the total vehicles were cars and vans. There were 156 lorries and thrice as many cars as vans. How many more cars than vans were there?
Cars |
Vans |
Lorries |
5x4 |
3x4 |
3x5 |
1x5 |
|
15 u |
5 u |
12 u |
The total number of cars and vans is repeated. Make the total number of cars and vans the same. LCM of 5 and 4 is 20.
Number of lorries = 12 u
12 u = 156
1 u = 156 ÷ 12 = 13
Number of more cars than vans
= 15 u - 5 u
= 10 u
= 10 x 13
= 130
Answer(s): 130
