A bakery made some egg, beef and kaya sandwiches. For every 2 egg sandwiches that were made, 1 kaya sandwich were made. For every 5 egg sandwiches that were made, 4 beef sandwiches were made.
- Find the ratio of the number of egg sandwiches to beef sandwiches to kaya sandwiches made.
- After the bakery made another 100 kaya sandwiches, 25% of the sandwiches now were kaya sandwiches. How many egg sandwiches did the bakery make?
(a)
Egg |
Beef |
Kaya |
2x5 |
|
1x5 |
5x2 |
4x2 |
|
10 u |
8 u |
5 u |
Egg : Beef : Kaya
10 : 8 : 5
(b)
|
Egg |
Beef |
Kaya |
Before |
18 u |
5 u |
Change |
No change |
+ 100 |
After |
3x6 = 18 u |
1x6 = 6 u |
Total number of egg and beef sandwiches
= 8 u + 10 u
= 18 u
Increase in the number of kaya sandwiches
= 6 u - 5 u
= 1 u
1 u = 100
Number of egg sandwiches
= 10 u
= 10 x 100
= 1000
Answer(s): (a) 10 : 8 : 5 ; (b) 1000
