    Question

    A man invested Rs. 16,000 at simple interest of 'x%'

    p.a. and received Rs. 32,000 after 2 years. If he had invested Rs. 21,000 at simple interest of 'x%' p.a. for 3 years, then find the interest earned by him from this investment
    A Rs. 31200 Correct Answer Incorrect Answer
    B Rs. 31300 Correct Answer Incorrect Answer
    C Rs. 31700 Correct Answer Incorrect Answer
    D Rs. 31500 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Total interest earned in 2 years = 32000 - 16000 = Rs. 16000 ATQ; 16000 = (16000 × x × 2) ÷ 100 Or, x = 50 So, required interest earned = (21,000 × 50 × 3) ÷ 100 = Rs. 31500
