Show answerHide answer

Answer: D

Approach: E = I ÷ (1 + P/100); incomes equal.

Solution: From the graph, 2009: X = 50%, Y = 60%.
EX = I/1.5, EY = I/1.6.
EX : EY = 1/1.5 : 1/1.6 = 1.6 : 1.5 = 16 : 15.

Why the other options are wrong: 15:16 (E) results from reading X as 60% and Y as 50%; 6:5 / 5:6 ignore the '1 +' in the income formula.

Cetking shortcut: X has the lower profit %, so X must spend more → ratio > 1 → only 6:5, 11:6, 16:15 survive; 160:150 = 16:15.

Answer: D
