Q. 80
A man buys a scooter on making a cash down payment of Rs 16224 and promises to pay two more yearly instalments of an equivalent amount in the next two years. If the rate of interest is 4% per annum, compounded yearly, the cash value of the scooter is
(A) Rs 40000
(B) Rs 46824
(C) Rs 46000
(D) Rs 50000
Answer: (B) Rs 46824
Explanation: Let the principal for the first year = X, and the principal for the second year = Y
Now, 16224 = X(1 + 4/100); X= 15600
And, 16224 = Y(1 + 4/100)², Y = 15000
Cash value of the scooter = (16224 + 15600 + 15000) = 46, 824
