    Rs. (n + 500) invested on simple interest amounts to Rs.

    4,500 and Rs. 5,100 in 5 years and 6 years, respectively. Find the value of 'n'.

    B 1500 Correct Answer Incorrect Answer
    C 1240 Correct Answer Incorrect Answer
    D 1150 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, Interest earned in 1 year = 5,100 - 4,500 = Rs. 600
    Interest earned in 5 years = 600 × 5 = Rs. 3,000
    So, n + 500 = 4,500 - 3,000
    Or, n + 500 = 1,500
    Or, n = 1,000
