Alia and Huda have some sweets in the ratio 7:3. Alia gives 3 sweets to Huda and now the ratio is 5:3. How many sweets did each have initially?

A/H =7/3,   

(A - 3) / (H + 3) =5 / 3, solve for A, H

 

Alia had 28 and Huda had 12 initially.

7/ (7+3) x      -3    = 5/(5+3) x

solve for x = total amount = 40

 

7 / 10   * 40 = 28

3/10 * 40    = 12      initially
