Question 936017
ratio of shares of A,B,C  = 7:1:3
A'share  =7 * some constant
        = 7*x
B'share  = x
C'share  = 3 x
total  = 7x+x+3x =11x
but total amount  = 7500
 11 x =7500
 divide with 11 on both sides
 {{{ 11x/11  =7500/11}}}
           x = 7500/11
              = 681.81 
Hence B receives an amount of  Rs. 681.81
