A bakery made some egg, beef and chicken muffins. For every 2 egg muffins that were made, 1 chicken muffin were made. For every 5 egg muffins that were made, 4 beef muffins were made.
- Find the ratio of the number of egg muffins to beef muffins to chicken muffins made.
- After the bakery made another 67 chicken muffins, 25% of the muffins now were chicken muffins. How many egg muffins did the bakery make?
(a)
Egg |
Beef |
Chicken |
2x5 |
|
1x5 |
5x2 |
4x2 |
|
10 u |
8 u |
5 u |
Egg : Beef : Chicken
10 : 8 : 5
(b)
|
Egg |
Beef |
Chicken |
Before |
18 u |
5 u |

No change |
+ 67 |
After |
3x6 = 18 u |
1x6 = 6 u |
Total number of egg and beef muffins
= 8 u + 10 u
= 18 u
Increase in the number of chicken muffins
= 6 u - 5 u
= 1 u
1 u = 67
Number of egg muffins
= 10 u
= 10 x 67
= 670
Answer(s): (a) 10 : 8 : 5 ; (b) 670
