A24
B42 ✓ Correct
C56
D68
Correct answer: (B) 42
Explanation
The answer is 42.
State B has 28 percent of 1400, which is 392 cars, and its diesel share of 5 in 14 is 140.
State D has 26 percent of 1400, which is 364 cars, and its petrol share of 1 in 2 is 182.
So the difference is 182 minus 140.
That equals 42.
So the diesel cars in B and the petrol cars in D differ by 42.
So the answer is 42.
