A. 15%
B. 32%
C. 40%
D. 62%
E. 80%

OA B

Say, the profit in March was $100.

Thus,

Profit in April = $100 + 10% of 100 = $110;
Profit in May = $110 – 20% of 110 = $88;
Profit in June = $88 + 50% of 88 = $132

Thus, the profit rose by 132 – 100 = 32%

The correct answer: B

Hope this helps!

We can let the profit in March be 100. So the profit in April is 100 x 1.1 = 110; the profit in May is 110 x 0.8 = 88; and the profit in June is 88 x 1.5 = 132, which is a 32% increase from 100.

Answer: B
