Hi,

Can anyone help me in resolving this problem? I know it is simple. But I'm missing a small step somewhere.....

A total of n trucks and cars are parked in a lot. If the number of cars is 1/4 the number of trucks, and 2/3 of the trucks are pickups, how many pickups, in terms of n, are parked in the lot?
(A) 1n/6
(B) 5n/12
(C) 1n/2
(D) 8n/15
(E) 11n/12

Lets consider the number of trucks = x
Hence, total number of cars is = x/4
from the question we know, x+x/4 = n = > x = 4n/5
Number of trucks that are pickups = (2/3)4n/5 = 8n/15.
D is the answer.

Cheers!
