    A certain sum of money becomes 4000 in 6 years and Rs.

    5000 in 10 years at any certain rate of simple interest. Find the principal amount.
    A Rs. 2000 Correct Answer Incorrect Answer

    C Rs. 2700 Correct Answer Incorrect Answer
    D Rs. 2800 Correct Answer Incorrect Answer

    Solution

    Simple interest for 4 years = 5000 – 4000 = Rs. 1000 Simple interest for 1 year = 1000/4 = Rs. 250 Simple interest for 6 years = 250 × 6 = Rs. 1500 So, required principal amount = 4000 – 1500 = Rs. 2500
