Difference |
| Before |
6x3 =
18 u |
5x3 =
15 u |
1x3 =
3 u |
| Change |
- -2 u |
- -2 u |
|
| After |
20 u |
17 u |
3 u |
100% - 15% = 85%
85% =
85100 =
1720The difference in the number of custard and chocolate croissants remains unchanged.
LCM of 1 and 3 = 3
Total croissants left = 20 u + 17 u = 37 u
37 u = 148
1 u = 148 ÷ 37 = 4
Total number of each type of croissants eaten
= -2 u
= -2 x 4
= -8
Answer(s): -8
