Solution
The correct option is A 3000 In compound interest, interest is calculated where the principal of the next year includes all of the accumulated interest from previous periods. It is nothing but 'Interest on interest' So the principal amount for the second year will be the amount obtained after the first year i.e, interest will be calculated on this amount = ₹ 3000
