A bakery made some beef, sardine and lotus paste muffins. For every 2 beef muffins that were made, 1 lotus paste muffin were made. For every 8 beef muffins that were made, 7 sardine muffins were made.
- Find the ratio of the number of beef muffins to sardine muffins to lotus paste muffins made.
- After the bakery made another 41 lotus paste muffins, 25% of the muffins now were lotus paste muffins. How many beef muffins did the bakery make?
(a)

8 u |
7 u |

Beef : Sardine : Lotus Paste
8 : 7 : 4
(b)

No change |
+ 41 |
After |
3x5 = 15 u |
1x5 = 5 u |
Total number of beef and sardine muffins
= 7 u + 8 u
= 15 u
Increase in the number of lotus paste muffins
= 5 u - 4 u
= 1 u
1 u = 41
Number of beef muffins
= 8 u
= 8 x 41
= 328
Answer(s): (a) 8 : 7 : 4 ; (b) 328
