A bakery made some chocolate, curry and egg sandwiches. For every 2 chocolate sandwiches that were made, 1 egg sandwich were made. For every 5 chocolate sandwiches that were made, 4 curry sandwiches were made.
- Find the ratio of the number of chocolate sandwiches to curry sandwiches to egg sandwiches made.
- After the bakery made another 33 egg sandwiches, 25% of the sandwiches now were egg sandwiches. How many chocolate sandwiches did the bakery make?
(a)
Chocolate |
Curry |
Egg |

1x5 |
5x2 |
4x2 |
|
10 u |
8 u |
5 u |
Chocolate : Curry : Egg
10 : 8 : 5
(b)
|
Chocolate |
Curry |
Egg |
Before |

No change |
+ 33 |
After |
3x6 = 18 u |
1x6 = 6 u |
Total number of chocolate and curry sandwiches
= 8 u + 10 u
= 18 u
Increase in the number of egg sandwiches
= 6 u - 5 u
= 1 u
1 u = 33
Number of chocolate sandwiches
= 10 u
= 10 x 33
= 330
Answer(s): (a) 10 : 8 : 5 ; (b) 330
