    Chaman had a total of Rs 2600, a part of it he deposited in Bank A and the remaining amount in the bank B. Banks A and B pay simple interest at the rate of \[5\frac{1}{2}%\] and \[7\frac{1}{2}%\] respectively. After a certain time he receives same interests from both banks, then the amount invested in Bank B was -

    A) Rs 1500                        

    B) Rs 1200

    C) Rs 1400                        

    D) Rs 1100

    Correct Answer: D

    Solution :

    If the interest and time are same \[\frac{{{P}_{1}}}{{{P}_{2}}}=\frac{{{r}_{2}}}{{{r}_{1}}}\] Where P1 and P2 are two principals \[\frac{{{P}_{1}}}{{{P}_{2}}}=\frac{\frac{15}{2}}{\frac{11}{2}}=\frac{15}{11}=15:11\] Amount deposited in Bank B \[=\,\,\,\,\,\,\,\,\frac{11}{(15+11)}\times 2600\]= Rs 1100
