In the inventory at a certain car dealership, 2/3 of the cars are four-door sedans and 2/5 of the rest are SUVs. If the remaining 24 vehicles are pickup trucks, how many vehicles are in the inventory at the car dealership?

A. 60
B. 90
C. 120
D. 180
E. 240


Let us consider the total number of cars at the dealership be x.

Hence:
4 door sedans = 2x/3
SUVs = (x/3)*2/5 = 2x/15
Remaining cars = (x/3)*(3/5) = x/5

We have been told that x/5 = 24
=> x = 120

Hence C is the correct answer.

let total cars = x
so sedan ; 2x/3
left x/3 * 2/5 = SUV; 2x/15
now remaing cars
x/3 * 3/5 = x/5
x/5 = 24 ; x = 120
IMO C
