5000 at the rate of 18% p.a., 22% p.a. and 40% p.a., respectively for 6 years, 5 years and 3 years, respectively. Find the sum of simple interests received by them.Solution
ATQ, Simple interest received by ‘J’ = (5000 × 18 × 6)/100 = Rs. 5400 Simple interest received by ‘K’ = (5000 × 22 × 5)/100 = Rs. 5500 Simple interest received by ‘L’ = (5000 × 40 × 3)/100 = Rs. 6000 Required sum = (5000/100) × {(18 × 6) + (22 × 5) + (40 × 3)} = Rs. 16900
