A bakery made some chicken, lotus paste and beef croissants. For every 2 chicken croissants that were made, 1 beef croissant were made. For every 8 chicken croissants that were made, 7 lotus paste croissants were made.
- Find the ratio of the number of chicken croissants to lotus paste croissants to beef croissants made.
- After the bakery made another 84 beef croissants, 25% of the croissants now were beef croissants. How many chicken croissants did the bakery make?
(a)
Chicken |
Lotus Paste |
Beef |
2x4 |
|
1x4 |
8x1 |
7x1 |
|
8 u |
7 u |
4 u |
Chicken : Lotus Paste : Beef
8 : 7 : 4
(b)
|
Chicken |
Lotus Paste |
Beef |
Before |
15 u |
4 u |
Change |
No change |
+ 84 |
After |
3x5 = 15 u |
1x5 = 5 u |
Total number of chicken and lotus paste croissants
= 7 u + 8 u
= 15 u
Increase in the number of beef croissants
= 5 u - 4 u
= 1 u
1 u = 84
Number of chicken croissants
= 8 u
= 8 x 84
= 672
Answer(s): (a) 8 : 7 : 4 ; (b) 672
