A bakery made some chocolate, beef and lotus paste buns. For every 2 chocolate buns that were made, 1 lotus paste bun were made. For every 5 chocolate buns that were made, 4 beef buns were made.
- Find the ratio of the number of chocolate buns to beef buns to lotus paste buns made.
- After the bakery made another 75 lotus paste buns, 25% of the buns now were lotus paste buns. How many chocolate buns did the bakery make?
(a)
Chocolate |
Beef |
Lotus Paste |
2x5 |
|
1x5 |
5x2 |
4x2 |
|
10 u |
8 u |
5 u |
Chocolate : Beef : Lotus Paste
10 : 8 : 5
(b)
|
Chocolate |
Beef |
Lotus Paste |
Before |
18 u |
5 u |
Change |
No change |
+ 75 |
After |
3x6 = 18 u |
1x6 = 6 u |
Total number of chocolate and beef buns
= 8 u + 10 u
= 18 u
Increase in the number of lotus paste buns
= 6 u - 5 u
= 1 u
1 u = 75
Number of chocolate buns
= 10 u
= 10 x 75
= 750
Answer(s): (a) 10 : 8 : 5 ; (b) 750
