Correct Answer: Only II
Solution : I. The income of P in year Y1 is 200 and the income of Q in year Y1 is 250. So, the income of P is indeed 20 percent less than the income of Q in year Y1. $\therefore$ Statement I is correct. II. The total income of P over all years is 200 + 350 + 500 + 650 + 600 + 450 + 400 = 3150. The total income of Q over all years is 250 + 150 + 650 + 450 + 550 + 700 + 500 = 3250. So, the ratio of the total income of P to the total income of Q in all years is 3150 : 3250 = 63 : 65, not 63 : 64. $\therefore$ statement II is not correct. Hence, the correct answer is Only II.
