A bakery made some chicken, egg and mushroom buns. For every 2 chicken buns that were made, 1 mushroom bun were made. For every 5 chicken buns that were made, 4 egg buns were made.
- Find the ratio of the number of chicken buns to egg buns to mushroom buns made.
- After the bakery made another 75 mushroom buns, 25% of the buns now were mushroom buns. How many chicken buns did the bakery make?
(a)
Chicken |
Egg |
Mushroom |
2x5 |
|
1x5 |
5x2 |
4x2 |
|
10 u |
8 u |
5 u |
Chicken : Egg : Mushroom
10 : 8 : 5
(b)
|
Chicken |
Egg |
Mushroom |
Before |
18 u |
5 u |

No change |
+ 75 |
After |
3x6 = 18 u |
1x6 = 6 u |
Total number of chicken and egg buns
= 8 u + 10 u
= 18 u
Increase in the number of mushroom buns
= 6 u - 5 u
= 1 u
1 u = 75
Number of chicken buns
= 10 u
= 10 x 75
= 750
Answer(s): (a) 10 : 8 : 5 ; (b) 750
