StateCars (%)Diesel:Petrol

B285:9
C325:3
D261:1

The number of petrol engine cars in State C is what percent more than the number of diesel engine cars in State A?

A100% ✓ Correct
B125%
C200%
D120%
Correct answer: (A) 100%
Explanation

The answer is 100 percent.

State C has 32 percent of 1400, which is 448 cars, and its petrol share of 3 in 8 is 168.

State A has 14 percent of 1400, which is 196 cars, and its diesel share of 3 in 7 is 84.

So the excess is 168 minus 84, which is 84.

As a percent of 84 this is 84 divided by 84, times 100.

That is 100 percent.

So the answer is 100 percent.
