A car dealership has 40 cars on the lot, 30% of which are silver. If the dealership receives a new shipment of 80 cars, 40% of which are not silver, what percentage of total number of cars are silver?

Number of silver cars before shipment = 30% of 40 = 12 Number of silver cars after shipment = 60% of 80 = 48 Total number of silver cars out of 120 = 48+12 = 60, which is 50% E is my answer.

There is a typo in the question... It s said to be 40% of the 80 received that are silver and in your calculation you ve used 60%... So i stucked at 36.67% which is none of the answers.

No typo there. We are told that 40% of 80 cars are NOT silver, thus remaining 60% are silver.

A. 35% B. 37.5% C. 45% D. 47.5% E. 50%

The number of silver cars is 0.3*40+0.6*80=60, which is 60/(40+80)=1/2=50% of total number of cars.

Answer: E.

Hope it's clear.
