    The money becomes RS. 2, 240 in 2 years by simple interest and in 5 years, it becomes RS.2, 600. so much is the money?

    A) RS. 2, 000                    

    B) RS. 2, 120

    C) RS. 1, 880                    

    D) None of these

    Correct Answer: A

    Solution :

    Let the money is Rs.x. Then,    \[2600-2240=\frac{x\times 3\times r}{100}\] \[360=\frac{x\times 3\times r}{100}\] \[xr=12,000\] Now,     \[2240-x=\frac{xr\times 2}{100}\] \[2240-x=\frac{12000\times 2}{100}\] \[2240-x=240\] \[x=Rs.2,000\]
