A bakery made some chocolate, egg and kaya sandwiches. For every 2 chocolate sandwiches that were made, 1 kaya sandwich were made. For every 8 chocolate sandwiches that were made, 7 egg sandwiches were made.
- Find the ratio of the number of chocolate sandwiches to egg sandwiches to kaya sandwiches made.
- After the bakery made another 49 kaya sandwiches, 25% of the sandwiches now were kaya sandwiches. How many chocolate sandwiches did the bakery make?
(a)
Chocolate |
Egg |
Kaya |
2x4 |
|
1x4 |
8x1 |
7x1 |
|
8 u |
7 u |
4 u |
Chocolate : Egg : Kaya
8 : 7 : 4
(b)
|
Chocolate |
Egg |
Kaya |
Before |
15 u |
4 u |
Change |
No change |
+ 49 |
After |
3x5 = 15 u |
1x5 = 5 u |
Total number of chocolate and egg sandwiches
= 7 u + 8 u
= 15 u
Increase in the number of kaya sandwiches
= 5 u - 4 u
= 1 u
1 u = 49
Number of chocolate sandwiches
= 8 u
= 8 x 49
= 392
Answer(s): (a) 8 : 7 : 4 ; (b) 392
