An amount of 'a' is invested at an annual interest rate
of 18% with simple interest, and another amount of 'a + 750' is invested at an annual interest rate of 24% with simple interest. After a period of 3 years, the combined interest earned from both investments amounts to Rs. 2052.determine the value of 'a' under these conditions.Solution
According to question,  a × 0.18 × 3 + (a + 750) × 0.24 × 3 = 2052  Or, 0.18a + 0.24a + 180 = 684  Or, 0.42a = 504  Or, a = 1200
