Re: In a certain parking lot, 3% of the cars are towed for parking [#permalink]
Carcass, and KarunMendiratta, can you please clarify why % cars parked illegally in the parking = 3/20 and not 3/100 , percentage of total cars parked illegally rather than total #of cars?

80% of the cars which are parked illegally are not towed.
So, 20% of the cars which are parked illegally are towed
--> 20% of X = 3
--> 0.2X = 3
--> X = 15

B is the answer
