Hi,

a man has a bag of sweets he gave 1 sweet to his son then he gave 1/7 of remaining sweets to his son. Then he gave 2 sweets to his daughter then he he gave 1/7 of remaining to his daughter. Both child got equal numbers of sweets.

Let 'T' represent the total sweets in the bag.  

     Son: 

Daughter: 

Question states***Both child got equal numbers of sweets.



  7S = 14 + T - 2 - S

  8S - 12 = T

   |Substitute for T

    7S = 7 + 8S - 13

      S = 6  (D=6)   and T = 36 total sweets in the bag  (8S -12)
