A bakery made some mushroom, beef and chicken buns. For every 2 mushroom buns that were made, 1 chicken bun were made. For every 8 mushroom buns that were made, 7 beef buns were made.
- Find the ratio of the number of mushroom buns to beef buns to chicken buns made.
- After the bakery made another 89 chicken buns, 25% of the buns now were chicken buns. How many mushroom buns did the bakery make?
(a)
Mushroom |
Beef |
Chicken |
2x4 |
|
1x4 |
8x1 |
7x1 |
|
8 u |
7 u |
4 u |
Mushroom : Beef : Chicken
8 : 7 : 4
(b)
|
Mushroom |
Beef |
Chicken |
Before |
15 u |
4 u |
Change |
No change |
+ 89 |
After |
3x5 = 15 u |
1x5 = 5 u |
Total number of mushroom and beef buns
= 7 u + 8 u
= 15 u
Increase in the number of chicken buns
= 5 u - 4 u
= 1 u
1 u = 89
Number of mushroom buns
= 8 u
= 8 x 89
= 712
Answer(s): (a) 8 : 7 : 4 ; (b) 712
