Min, Usha and Xandra had lollipops in the ratio of 7 : 2 : 3. After Min gave 27 lollipops to Usha and Xandra, the three of them had the same number of lollipops. Find the total number of lollipops the children had.

| After |
4 u |

4 u |
12 u |
Total number of lollipops
= 7 u + 2 u + 3 u
= 12 u
Number of lollipops that each had in the end
= 12 u ÷ 3
= 4 u
Number of lollipops that Min gave to Usha and Xandra
= 7 u - 4 u
= 3 u
3 u = 27
1 u = 27 ÷ 3 = 9
Total number of lollipops
= 12 u
= 12 x 9
= 108
Answer(s): 108
