Divide Rs. 1301 between A and B, so that the amount of A after 7 years is equal to the amount of B after 9 years, the interest being compounded at 4% per annum.

Let the two parts be Rs. x and Rs. (1301 - x).

  $x1+\frac{4}{100}7=1301-x1+\frac{4}{100}9$

  $\frac{x}{1301-x}=1+\frac{4}{100}2=\frac{26}{25}*\frac{25}{26}$

=> 625x=676(1301-x) 

1301x=676 x 1301x=676.
So,the parts are rs.676 and rs.(1301-676)i.e rs.676 and rs.625
