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 kaya buns remains unchanged.
LCM of 1 and 2 = 2
Total buns left = 5 u + 3 u = 8 u
8 u = 184
1 u = 184 ÷ 8 = 23
Total number of each type of buns eaten
= 7 u
= 7 x 23
= 161
Answer(s): 161
