A212
B224
C204
D196 ✓ Correct
Correct answer: (D) 196
Explanation
The answer is 196.
State C has 32 percent of 1400, which is 448 cars.
State B has 392 cars, and its petrol share of 9 in 14 is 252.
So the difference is 448 minus 252.
That equals 196.
So the total cars in C exceed the petrol cars in B by 196.
So the answer is 196.
