A bakery made some egg, chocolate and beef muffins. For every 2 egg muffins that were made, 1 beef muffin were made. For every 8 egg muffins that were made, 7 chocolate muffins were made.
- Find the ratio of the number of egg muffins to chocolate muffins to beef muffins made.
- After the bakery made another 70 beef muffins, 25% of the muffins now were beef muffins. How many egg muffins did the bakery make?
(a)
Egg |
Chocolate |
Beef |
2x4 |
|
1x4 |
8x1 |
7x1 |
|
8 u |
7 u |
4 u |
Egg : Chocolate : Beef
8 : 7 : 4
(b)
|
Egg |
Chocolate |
Beef |
Before |
15 u |
4 u |
Change |
No change |
+ 70 |
After |
3x5 = 15 u |
1x5 = 5 u |
Total number of egg and chocolate muffins
= 7 u + 8 u
= 15 u
Increase in the number of beef muffins
= 5 u - 4 u
= 1 u
1 u = 70
Number of egg muffins
= 8 u
= 8 x 70
= 560
Answer(s): (a) 8 : 7 : 4 ; (b) 560
