The sum that amounts to Rs.4913 in 3 years at (25/4)% per annum compounded annually, is
Amount, A = Rs.4913
Interest rate, R = (25/4)% per annum
Time = 3 years
Amount (A) = P (1 + R/100)n
⇒ 4913 = P (1 + (25/4)/100)3
⇒ 4913 = P (1 + 1/16)3
⇒ 4913 = P (17/16)3
⇒ 4913 = P × 4913/4096
⇒ P = 4913 × 4096/4913
⇒ P = 4096
∴ Sum = Rs.4096
