    A certain sum of money becomes Rs. 1900 in 1 year and

    2600 in 3 years at certain rate of simple interest. Find the sum of money invested.

    D Rs. 1450 Correct Answer Incorrect Answer

    Solution

    Interest earned in 2 years = 2600 – 1900 = Rs. 700 So the interest earned in 1 year = 700/2 = Rs. 350 So, the sum of money invested = 1900 – 350 = Rs. 1550
