Difference |
Before |
7x2 = 14 u |
6x2 = 12 u |
1x2 = 2 u |
Change |
- 9 u |
- 9 u |

After |
5 u |
3 u |
2 u |
100% - 40% = 60%
60% =
60100 =
35The difference in the number of kaya and chocolate buns remains unchanged.
LCM of 1 and 2 = 2
Total buns left = 5 u + 3 u = 8 u
8 u = 136
1 u = 136 ÷ 8 = 17
Total number of each type of buns eaten
= 9 u
= 9 x 17
= 153
Answer(s): 153
