Ratio of the capitals of A, Band C

                     = 20000 x 5 + 15000 x 7 : 20000 x 5 + 16000 x 7 : 20000 x 5 + 26000 x 7

                    = 205000:212000 : 282000 = 205 : 212 : 282.

         A’s share = Rs. 69900 x (205/699) = Rs. 20500                     I

        B's share = Rs. 69900 x (212/699) = Rs. 21200;

       C's share = Rs. 69900 x (282/699) = Rs. 28200.
