    Arun borrowed some money from Jayant. Rate of simple interest is 8% p.a. for first 4 years, 10% per annum for next 6 years and 12% p.a. is for the time there after. If Jayant paid a total of Rs.12160 as simple interest after 15 years, then the sum he borrowed was

    A)  \[Rs.8000\]     

    B)  \[Rs.10000\]

    C)  \[Rs.12000\]               

    D)  \[Rs.9000\]

    Correct Answer: A

    Solution :

     Time of 12% p.a. interest \[=15-(6+4)=5\] years Now, \[\frac{P\times 4\times 8}{100}+\frac{P\times 6\times 10}{100}+\frac{P\times 5\times 12}{100}\] \[=Rs.\,\,12160\] \[32P+60P+60P=12160\times 100\] \[P=\frac{12160\times 100}{152}=\]
