A bakery made some mushroom, chocolate and beef buns. For every 2 mushroom buns that were made, 1 beef bun were made. For every 5 mushroom buns that were made, 4 chocolate buns were made.
- Find the ratio of the number of mushroom buns to chocolate buns to beef buns made.
- After the bakery made another 84 beef buns, 25% of the buns now were beef buns. How many mushroom buns did the bakery make?
(a)
Mushroom |
Chocolate |
Beef |
2x5 |
|
1x5 |
5x2 |
4x2 |
|
10 u |
8 u |
5 u |
Mushroom : Chocolate : Beef
10 : 8 : 5
(b)
|
Mushroom |
Chocolate |
Beef |
Before |
18 u |
5 u |
Change |
No change |
+ 84 |
After |
3x6 = 18 u |
1x6 = 6 u |
Total number of mushroom and chocolate buns
= 8 u + 10 u
= 18 u
Increase in the number of beef buns
= 6 u - 5 u
= 1 u
1 u = 84
Number of mushroom buns
= 10 u
= 10 x 84
= 840
Answer(s): (a) 10 : 8 : 5 ; (b) 840
