A bakery made some beef, chocolate and mushroom croissants. For every 2 beef croissants that were made, 1 mushroom croissant were made. For every 5 beef croissants that were made, 4 chocolate croissants were made.
- Find the ratio of the number of beef croissants to chocolate croissants to mushroom croissants made.
- After the bakery made another 97 mushroom croissants, 25% of the croissants now were mushroom croissants. How many beef croissants did the bakery make?
(a)
Beef |
Chocolate |
Mushroom |
2x5 |
|
1x5 |
5x2 |
4x2 |
|
10 u |
8 u |
5 u |
Beef : Chocolate : Mushroom
10 : 8 : 5
(b)
|
Beef |
Chocolate |
Mushroom |
Before |
18 u |
5 u |
Change |
No change |
+ 97 |
After |
3x6 = 18 u |
1x6 = 6 u |
Total number of beef and chocolate croissants
= 8 u + 10 u
= 18 u
Increase in the number of mushroom croissants
= 6 u - 5 u
= 1 u
1 u = 97
Number of beef croissants
= 10 u
= 10 x 97
= 970
Answer(s): (a) 10 : 8 : 5 ; (b) 970
