A35
B27
C30
D32 ✓ Correct
Correct answer: (D) 32
Explanation
The answer is about 32 percent.
Physics is 22 percent of 750 plus 18.125 percent of 800, which is 165 plus 145, or 310.
Hindi is 14 percent of 750 plus 16.25 percent of 800, which is 105 plus 130, or 235.
The excess is 310 minus 235, which is 75.
So the percentage more is 75 divided by 235, times 100.
That is about 32 percent.
So the answer is 32.
