interest such that interest earned after 5 years is Rs. 600. If the amount received is further invested in scheme 'B' offering simple interest of 20% p.a. then the amount received after three years would be Rs. 1800. Find the value of 'x'.Solution
ATQ, Sum invested in scheme 'B' = Rs. x + 600 Amount received after 3 years = (x + 600) + (x + 600) × 0.20 × 3 = Rs. 1.60x + 960 According to the question, 1.60x + 960 = 1800 1.60x = 840 x = 525
