Profit in 1982 = 15.6 - 12 = 3.6 million $
Profit in 1983 = 18.8 - 14 = 4.8 million $

Percentage increase in profit = (4.8-3.6)/3.6 * 100 %
= 33.33 %

Answer D

(A) 3%
(B)16 2/3%
(C) 25%
(D) 33 1/3%
(E) 60%



Profit in 1982 = 15.6-12 = 3.6
Profit in 1983 = 18.8-14 = 4.8

so net increase in profit = 4.8 - 3.6 = 1.2
so % increase = 1.2/3.6 * 100 = 33.33%

Answer: option D

Profit = Revenue - operating expenses
Profit in 1982 = Revenue in 1982 - operating expenses in 1982
= $15.6 million - $12 million
= $3.6 million
Profit in 1983 = Revenue in 1983 - operating expenses in 1983
= $18.8 million - $14 million
= $4.8 million
Percentage increase in company B's profit from 1982 to 1983 = \(\frac{(4.8-3.6)}{3.6}\) * 100 = \(\frac{1.2}{3.6}\) * 100 = 33 \(\frac{1}{3}\) %
correct answer - D

The profit in 1982 was 15.6 - 12.0 = 3.6 million dollars, and, in 1983, the profit was 18.8 - 14.0 = 4.8 million dollars.

We use the formula for percent increase: (new - old)/old x 100. The percent increase from 1982 to 1983 was:

(4.8 - 3.6)/3.6 x 100

1.2/3.6 x 100

12/36 x 100 = 1/3 x 100 = 33 1/3%

Answer: D
