18 boys and 9 girls shared some sweets equally. Each boy gave 1/4 of his sweets to the girls. As a result, each girl received 12 more sweets than each boy. Find the total number of sweets shared at first.

Let the total number of sweets==C

Let the share of each boy and each girl=s

C/27==s.....................................(1)

18s - 1/4*(18s) ==9 [s +12].........(2), solve for s, C

Use substitution to get:

**C==648 - total number of sweets. s==24 sweets - originally shared by 18 boys and 9 girls each.**
