p.a. and received Rs. 45,000 after 2 years. If he had invested Rs. 30,000 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 = 45000 - 30000 = Rs. 15,000 ATQ; 15000 = (30000 × x × 2) ÷ 100 Or, x = 25 So, required interest earned = (30,000 × 25 × 3) ÷ 100 = Rs. 22500
