Joshua bought some chocolate and matcha muffins in the ratio of 5 : 4. After Joshua's classmates ate an equal number of the two types of muffins, there were 40% fewer matcha than chocolate muffins. In the end, there were 120 muffins left. How many muffins of each type were eaten?

Difference |
Before |
5x2 = 10 u |
4x2 = 8 u |
1x2 = 2 u |
Change |
- 5 u |
- 5 u |
|
After |
5 u |
3 u |
2 u |
100% - 40% = 60%
60% =
60100 =
35The difference in the number of chocolate and matcha muffins remains unchanged.
LCM of 1 and 2 = 2
Total muffins left = 5 u + 3 u = 8 u
8 u = 120
1 u = 120 ÷ 8 = 15
Total number of each type of muffins eaten
= 5 u
= 5 x 15
= 75
Answer(s): 75
