simple interest of 20% p.a. and reinvested the interest earned from scheme ‘A’ at the end of 4 years in scheme ‘B’ offering compound interest of 20% p.a. compounded annually. If total amount received from scheme ‘B’ after 2 years is Rs. 1440, then find the value of ‘13x’.Solution
According to question; 1.44 × {0.20 × 4 × 10x} = 1440 Or, {0.20 × 4 × 10x} = 1000 Or, x = 125 So, 13x = 13 × 125 = 1625
