    A man borrowed Rs. 40000 at 8% simple interest per year. At the end of second year he paid back certain amount and at the end of fifth year he paid back Rs. 35960 and cleared the debt. What is the amount did he pay after the second year?

    A) Rs. 16200                     

    B) Rs. 17400

    C) Rs. 18600                     

    D) None of these

    Correct Answer: B

    Solution :

    Total borrowed money \[=Rs.\,40000\] and rate of interest = 8 % The interest for \[2\,yr=\frac{40000\times 8\times 2}{100}\]                         \[=Rs.\,6400\] Let he paid Rs. x at the end of second year. Interest will be calculated on \[Rs.\,(40000-x+6400)\] Interest for \[3\,yr=\frac{(46400-x)\times 3\times 8}{100}\]             \[=Rs.\frac{6}{25}(46400-x)\] \[\therefore \]      \[\frac{6}{25}(46400-x)+46400-x=35960\] \[\Rightarrow \]   \[11136-\frac{6x}{25}+46400-x=35960\] \[\Rightarrow \]   \[\frac{31x}{25}=21576\] \[\Rightarrow \]   \[x=\frac{21576\times 25}{31}=Rs.17400\]
