Question
A man invested Rs. 7,000 at simple interest of 'x%' p.a.
and received Rs. 14,000 after 2 years. If he had invested Rs. 80,000 at simple interest of 'x%' p.a. for 3 years, then find the interest earned by him from this investmentSolution
Total interest earned in 2 years = 14000 - 7000 = Rs. 7,000 ATQ; 7000 = (7000 × x × 2) ÷ 100 Or, x = 50 So, required interest earned = (80,000 × 50 × 3) ÷ 100 = Rs. 120000
