Let the number of vehicles be 100
Number of vehicles rented = 70% = 70
Therefore, Number of vehicles not rented = 30

Now 60% of total vehicles contain 4wds i.e., 60 vehicles out of 100

3/5 ths of 60(4wds) is rented, so 2/5 th of 60 (4WDS) are not rented ie., 24

percent of the vehicles that were not rented were not 4WDs = (24/30)* 100 = 20%
