A bakery made some egg, lotus paste and chicken croissants. For every 2 egg croissants that were made, 1 chicken croissant were made. For every 8 egg croissants that were made, 7 lotus paste croissants were made.
- Find the ratio of the number of egg croissants to lotus paste croissants to chicken croissants made.
- After the bakery made another 99 chicken croissants, 25% of the croissants now were chicken croissants. How many egg croissants did the bakery make?
(a)
Egg |
Lotus Paste |
Chicken |
2x4 |
|
1x4 |
8x1 |
7x1 |
|
8 u |
7 u |
4 u |
Egg : Lotus Paste : Chicken
8 : 7 : 4
(b)
|
Egg |
Lotus Paste |
Chicken |
Before |
15 u |
4 u |
Change |
No change |
+ 99 |
After |
3x5 = 15 u |
1x5 = 5 u |
Total number of egg and lotus paste croissants
= 7 u + 8 u
= 15 u
Increase in the number of chicken croissants
= 5 u - 4 u
= 1 u
1 u = 99
Number of egg croissants
= 8 u
= 8 x 99
= 792
Answer(s): (a) 8 : 7 : 4 ; (b) 792
