A bakery made some egg, chicken and sardine buns. For every 2 egg buns that were made, 1 sardine bun were made. For every 8 egg buns that were made, 7 chicken buns were made.
- Find the ratio of the number of egg buns to chicken buns to sardine buns made.
- After the bakery made another 67 sardine buns, 25% of the buns now were sardine buns. How many egg buns did the bakery make?
(a)

Egg : Chicken : Sardine
8 : 7 : 4
(b)

+ 67 |
After |
3x5 = 15 u |
1x5 = 5 u |
Total number of egg and chicken buns
= 7 u + 8 u
= 15 u
Increase in the number of sardine buns
= 5 u - 4 u
= 1 u
1 u = 67
Number of egg buns
= 8 u
= 8 x 67
= 536
Answer(s): (a) 8 : 7 : 4 ; (b) 536
