A bakery made some sardine, egg and mushroom buns. For every 2 sardine buns that were made, 1 mushroom bun were made. For every 5 sardine buns that were made, 4 egg buns were made.
- Find the ratio of the number of sardine buns to egg buns to mushroom buns made.
- After the bakery made another 93 mushroom buns, 25% of the buns now were mushroom buns. How many sardine buns did the bakery make?
(a)
Sardine |
Egg |
Mushroom |
2x5 |
|
1x5 |
5x2 |
4x2 |
|
10 u |
8 u |
5 u |
Sardine : Egg : Mushroom
10 : 8 : 5
(b)
|
Sardine |
Egg |
Mushroom |
Before |
18 u |
5 u |

No change |
+ 93 |
After |
3x6 = 18 u |
1x6 = 6 u |
Total number of sardine and egg buns
= 8 u + 10 u
= 18 u
Increase in the number of mushroom buns
= 6 u - 5 u
= 1 u
1 u = 93
Number of sardine buns
= 10 u
= 10 x 93
= 930
Answer(s): (a) 10 : 8 : 5 ; (b) 930
