Question
Rs. 5000 is invested in scheme ‘A’ for 2 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’ = 5000 × 16 × 2 ÷ 100 = Rs. 1600 Let the rate of simple interest offered by scheme ‘B’ = ‘k%’ p.a. ATQ; 8000 × 2 × k ÷ 100 = 1600 Or, 160k = 1600 Or, k = (1600/160) = 10 So, rate of simple interest offered by scheme ‘B’ = 10% per annum.
