Risa, Min and Lynn had lollipops in the ratio of 10 : 5 : 3. After Risa gave 24 lollipops to Min and Lynn, the three of them had the same number of lollipops. Find the total number of lollipops the children had.

18 u |
Total number of lollipops
= 10 u + 5 u + 3 u
= 18 u
Number of lollipops that each had in the end
= 18 u ÷ 3
= 6 u
Number of lollipops that Risa gave to Min and Lynn
= 10 u - 6 u
= 4 u
4 u = 24
1 u = 24 ÷ 4 = 6
Total number of lollipops
= 18 u
= 18 x 6
= 108
Answer(s): 108
