A bakery made some kaya, chocolate and sardine buns. For every 2 kaya buns that were made, 1 sardine bun were made. For every 8 kaya buns that were made, 7 chocolate buns were made.
- Find the ratio of the number of kaya buns to chocolate buns to sardine buns made.
- After the bakery made another 65 sardine buns, 25% of the buns now were sardine buns. How many kaya buns did the bakery make?
(a)
Kaya |
Chocolate |
Sardine |
2x4 |
|
1x4 |
8x1 |
7x1 |
|
8 u |
7 u |
4 u |
Kaya : Chocolate : Sardine
8 : 7 : 4
(b)
|
Kaya |
Chocolate |
Sardine |
Before |
15 u |
4 u |

No change |
+ 65 |
After |
3x5 = 15 u |
1x5 = 5 u |
Total number of kaya and chocolate buns
= 7 u + 8 u
= 15 u
Increase in the number of sardine buns
= 5 u - 4 u
= 1 u
1 u = 65
Number of kaya buns
= 8 u
= 8 x 65
= 520
Answer(s): (a) 8 : 7 : 4 ; (b) 520
