In each of the following questions, a question is followed by two statements. Read both the statements and find which statements are required to answer the question and answer accordingly. If Amit's and Bimal's annual salaries in 2021 were each 20% higher than their respective annual salaries in 2020, what was Amit's annual salary in 2020? Statement I: The sum of Amit's and Bimal's annual salaries in 2021 was Rs. 6,60,000. Statement II: The sum of Amit's and Bimal's annual salaries in 2020 was Rs. 5,00,000.

Let the annual salary of Amit in 2020 be Rs. A and the annual salary of Bimal in 2020 be Rs. B. ATQ, Amit's salary in 2021 = 1.20A and Bimal's salary in 2021 = 1.20B. From Statement I, the sum of Amit's and Bimal's annual salaries in 2021 was Rs. 6,60,000. Or, 1.20A + 1.20B = 6,60,000 Or, 1.20(A + B) = 6,60,000 So, A + B = 5,50,000 From Statement II, the sum of Amit's and Bimal's annual salaries in 2020 was Rs. 5,00,000. So, A + B = 5,00,000 From Statement I and II, both the statements together contradict each other, as the sum of salaries in 2020 cannot be both Rs. 5,50,000 and Rs. 5,00,000. Even if we assume they are consistent, we only get the sum of their salaries in 2020, which is not sufficient to find Amit's individual salary. So, both statements together are not sufficient to answer the question. Hence, the correct answer is D.
