Question
A man invested Rs. 5,000 at simple interest of 'x%' p.a.
and received Rs. 12,000 after 2 years. If he had invested Rs. 25,000 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 = 12000 - 5000 = Rs. 7,000 ATQ; 7000 = (5000 × x × 2) ÷ 100 Or, x = 70 So, required interest earned = (25,000 × 70 × 3) ÷ 100 = Rs. 52500
