Anna bought some matcha and custard muffins in the ratio of 6 : 5. After Anna's classmates ate an equal number of the two types of muffins, there were 30% fewer custard than matcha muffins. In the end, there were 187 muffins left. How many muffins of each type were eaten?

Difference |
| Before |
6x3 =
18 u |
5x3 =
15 u |
1x3 =
3 u |
| Change |
- 8 u |
- 8 u |

| After |
10 u |
7 u |
3 u |
100% - 30% = 70%
70% =
70100 =
710The difference in the number of matcha and custard muffins remains unchanged.
LCM of 1 and 3 = 3
Total muffins left = 10 u + 7 u = 17 u
17 u = 187
1 u = 187 ÷ 17 = 11
Total number of each type of muffins eaten
= 8 u
= 8 x 11
= 88
Answer(s): 88
