Question
Rs. 9500 is invested in scheme ‘A’ for 3 years and
Rs. 8000 is invested in scheme ‘B’ for 2 years. Scheme ‘A’ offers simple interest of 16% p.a. If the interest received from both the schemes are equal, then find the rate of simple interest (p.a.) offered by scheme ‘B’.Solution
Interest received from scheme ‘A’ = 9500 × 16 × 3 ÷ 100 = Rs. 4560 Let the rate of simple interest offered by scheme ‘B’ = ‘k%’ p.a. ATQ; 8000 × 2 × k ÷ 100 = 4560 Or, 160k = 4560 Or, k = (4560/160) = 28.5 So, rate of simple interest offered by scheme ‘B’ = 28.5% per annum.
