Mr. P invested Rs. ‘4x’ in scheme ‘A’ offering simple interest of 25% 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. 5760, then find the value of ‘5x’.
According to question; 1.44 × {0.25 × 4 × 4x} = 5760 Or, {0.25 × 4 × 4x} = 4000 Or, x = 1000 So, 5x = 5 × 1000 = 5000
