Question
A sum of money is invested at an annual simple interest
rate of 15% for a period of 3 years, yielding a total interest of Rs. 1350. Determine the principal amount.Solution
ATQ,
Let the sum be Rs. P Simple interest received = {(P X R X T)/100} Or, 1350 = {(P X 15 X 3)/100} Or, P = {(1350 X 100)/ (15 X 3)} Or, P = 3000 Therefore, sum invested = Rs. 3000
