A bakery made some sardine, lotus paste and curry sandwiches. For every 2 sardine sandwiches that were made, 1 curry sandwich were made. For every 8 sardine sandwiches that were made, 7 lotus paste sandwiches were made.
- Find the ratio of the number of sardine sandwiches to lotus paste sandwiches to curry sandwiches made.
- After the bakery made another 42 curry sandwiches, 25% of the sandwiches now were curry sandwiches. How many sardine sandwiches did the bakery make?

+ 42 |
After |
3x5 = 15 u |
1x5 = 5 u |
Total number of sardine and lotus paste sandwiches
= 7 u + 8 u
= 15 u
Increase in the number of curry sandwiches
= 5 u - 4 u
= 1 u
1 u = 42
Number of sardine sandwiches
= 8 u
= 8 x 42
= 336
Answer(s): (a) 8 : 7 : 4 ; (b) 336
