(D) 32 %
(E) 29 %


Assume the revenue in 2000 to be 100. Then in 2003 it would be 140 and and in 2005 180, so from 2003 to 2005 it increased by (180-140)/140=40/140=2/7=~29%.

Answer: E.

A certain company reported that the revenue on sales increased 40 % from 2000 to 2003, and increased 80 % from 2000 to 2005. What was the approximate percent increase in revenue for this store from 2003 to 2005?

(A) 50 %
(B) 40 %
(C) 35 %
(D) 32 %
(E) 29 %

Let Revenue for year 2000 be = 100
Revenue increased 40% from 2000 to 2003 = 140% of 100 = \(\frac{140}{100}\) x 100 = 140
Revenue increased 80% from 2000 to 2005 = 180% of 100 = \(\frac{180}{100 x 100}\) = 180
Change in revenue from 2003 to 2005 = 180-140 = 40
Percentage increase = Change in revenue / Initial value x 100 = \(\frac{40}{140}\) x 100 = 28.571... (approximately) = 29%
Answer E...

We can let the sales in 2000 = x. Thus, sales in 2003 are 1.4x and sales in 2005 are 1.8x. Let’s now calculate the percentage increase from 2003 to 2005:

(1.8x - 1.4x)/1.4x = 0.4/1.4 = 4/14 = 0.285 x 100% ≈ 29%

Answer: E
