Question
Rs. 6500 is invested in scheme ‘A’ for 2 years and
Rs. 6500 is invested in scheme ‘B’ for 2 years. Scheme ‘A’ offers simple interest of 14% 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’ = 6500 × 14 × 2 ÷ 100 = Rs. 1820 Let the rate of simple interest offered by scheme ‘B’ = ‘k%’ p.a. ATQ; 6500 × 2 × k ÷ 100 = 1820 Or, 130k = 1820 Or, k = (1820/130) = 14 So, rate of simple interest offered by scheme ‘B’ = 14% per annum.
