Salik bought some vanilla and custard buns in the ratio of 6 : 5. After Salik's classmates ate an equal number of the two types of buns, there were 40% fewer custard than vanilla buns. In the end, there were 144 buns left. How many buns of each type were eaten?

Difference |
Before |
6x2 = 12 u |
5x2 = 10 u |
1x2 = 2 u |
Change |
- 7 u |
- 7 u |
|
After |
5 u |
3 u |
2 u |
100% - 40% = 60%
60% =
60100 =
35The difference in the number of vanilla and custard buns remains unchanged.
LCM of 1 and 2 = 2
Total buns left = 5 u + 3 u = 8 u
8 u = 144
1 u = 144 ÷ 8 = 18
Total number of each type of buns eaten
= 7 u
= 7 x 18
= 126
Answer(s): 126
