A bakery made some lotus paste, egg and sardine croissants. For every 2 lotus paste croissants that were made, 1 sardine croissant were made. For every 8 lotus paste croissants that were made, 7 egg croissants were made.
- Find the ratio of the number of lotus paste croissants to egg croissants to sardine croissants made.
- After the bakery made another 109 sardine croissants, 25% of the croissants now were sardine croissants. How many lotus paste croissants did the bakery make?
(a)
Lotus Paste |
Egg |
Sardine |
2x4 |
|
1x4 |
8x1 |
7x1 |
|
8 u |
7 u |
4 u |
Lotus Paste : Egg : Sardine
8 : 7 : 4
(b)
|
Lotus Paste |
Egg |
Sardine |
Before |
15 u |
4 u |
Change |
No change |
+ 109 |
After |
3x5 = 15 u |
1x5 = 5 u |
Total number of lotus paste and egg croissants
= 7 u + 8 u
= 15 u
Increase in the number of sardine croissants
= 5 u - 4 u
= 1 u
1 u = 109
Number of lotus paste croissants
= 8 u
= 8 x 109
= 872
Answer(s): (a) 8 : 7 : 4 ; (b) 872
