Show answer and explanation

Correct answer: (B) 16:17

Explanation

The chart gives P percentages 10,20,40,40,50,40, totaling two hundred; Q gives 20,30,30,50,60,60, totaling two hundred fifty. If annual investment is I, total revenue is investment plus profit: P=6I+2I=8I and Q=6I+2.5I=8.5I. Ratio=16:17, B. Comparing profit totals alone would omit invested capital.
