A bakery made some beef, kaya and lotus paste sandwiches. For every 2 beef sandwiches that were made, 1 lotus paste sandwich were made. For every 8 beef sandwiches that were made, 7 kaya sandwiches were made.
- Find the ratio of the number of beef sandwiches to kaya sandwiches to lotus paste sandwiches made.
- After the bakery made another 26 lotus paste sandwiches, 25% of the sandwiches now were lotus paste sandwiches. How many beef sandwiches did the bakery make?
(a)
Beef |
Kaya |
Lotus Paste |
2x4 |
|
1x4 |
8x1 |
7x1 |
|
8 u |
7 u |
4 u |
Beef : Kaya : Lotus Paste
8 : 7 : 4
(b)
|
Beef |
Kaya |
Lotus Paste |
Before |
15 u |
4 u |
Change |
No change |
+ 26 |
After |
3x5 = 15 u |
1x5 = 5 u |
Total number of beef and kaya sandwiches
= 7 u + 8 u
= 15 u
Increase in the number of lotus paste sandwiches
= 5 u - 4 u
= 1 u
1 u = 26
Number of beef sandwiches
= 8 u
= 8 x 26
= 208
Answer(s): (a) 8 : 7 : 4 ; (b) 208
