| Before |
7x3 =
21 u |
6x3 =
18 u |
1x3 =
3 u |
| Change |

| After |
20 u |
17 u |
3 u |
100% - 15% = 85%
85% =
85100 =
1720The difference in the number of chocolate and kaya buns remains unchanged.
LCM of 1 and 3 = 3
Total buns left = 20 u + 17 u = 37 u
37 u = 185
1 u = 185 ÷ 37 = 5
Total number of each type of buns eaten
= 1 u
= 1 x 5
= 5
Answer(s): 5
