    A sum of money (P) doubles in 10 yr. In how many years it will be triple at the same rate of simple interest?

    A)  10 yr  

    B)         15 yr   

    C)         20 yr               

    D)         25 yr               

    Correct Answer: C

    Solution :

              \[A=2P\] \[\therefore \]      \[SI=P\]            \[(SI=2P-P)\] \[P=\frac{P\times r\times 10}{100}\] \[\therefore \]      \[r=10%\] So, the new amount = 3P But the new \[SI=2P=(3P-P)\] \[2P=\frac{P\times 10\times t}{100}\]                  (r = 10%) \[\therefore \]      \[t=20\,yr\]
