Start the planA 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?
A. 35%
B. 37.5%
C. 45%
D. 47.5%
E. 50%
The OA is E.
I solve this PS question as follows,
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%. Option E.
Please, can anyone explain another way to solve this question? Thanks in advance!
