Answer» Given, amount, A = ₹ 13924 time period , n = 2 interest rate , r = 18 % per annum Let principal is P use formula, so, 13924 = P(1 + 18/100)² => 13924 = P(118/100)² => P = 13924 × 10000/118 × 118 P = 10,000 hence, principal is ₹ 10, 000

Answer»

Given, amount, A = ₹ 13924 time period , n = 2 interest rate , r = 18 % per annum Let principal is P

use formula, so, 13924 = P(1 + 18/100)² => 13924 = P(118/100)² => P = 13924 × 10000/118 × 118 P = 10,000

hence, principal is ₹ 10, 000
