On a road the number of cars and the number of lorries are in the ratio 10 : 1 the number of lorries and the number of vans are in the ratio 7:10 There are 50 vans on the road. How many cars are there on the road?
7 / 10 = T / 50, solve for T
T = 35 trucks (lorries?)
Since the ratio of cars to trucks(lorries) = 10: 1, therefore:
There must be:35 x 10 = 350 cars 0n the road.

7 c / 1 v * 50 v = 350 cars
