A bakery made some beef, kaya and chocolate buns. For every 2 beef buns that were made, 1 chocolate bun were made. For every 8 beef buns that were made, 7 kaya buns were made.
- Find the ratio of the number of beef buns to kaya buns to chocolate buns made.
- After the bakery made another 60 chocolate buns, 25% of the buns now were chocolate buns. How many beef buns did the bakery make?
(a)
Beef |
Kaya |
Chocolate |
2x4 |
|
1x4 |
8x1 |
7x1 |
|
8 u |
7 u |
4 u |
Beef : Kaya : Chocolate
8 : 7 : 4
(b)
|
Beef |
Kaya |
Chocolate |
Before |
15 u |
4 u |
Change |
No change |
+ 60 |
After |
3x5 = 15 u |
1x5 = 5 u |
Total number of beef and kaya buns
= 7 u + 8 u
= 15 u
Increase in the number of chocolate buns
= 5 u - 4 u
= 1 u
1 u = 60
Number of beef buns
= 8 u
= 8 x 60
= 480
Answer(s): (a) 8 : 7 : 4 ; (b) 480
