A bakery made some curry, mushroom and sardine sandwiches. For every 2 curry sandwiches that were made, 1 sardine sandwich were made. For every 8 curry sandwiches that were made, 7 mushroom sandwiches were made.
- Find the ratio of the number of curry sandwiches to mushroom sandwiches to sardine sandwiches made.
- After the bakery made another 45 sardine sandwiches, 25% of the sandwiches now were sardine sandwiches. How many curry sandwiches did the bakery make?

+ 45 |
After |
3x5 = 15 u |
1x5 = 5 u |
Total number of curry and mushroom sandwiches
= 7 u + 8 u
= 15 u
Increase in the number of sardine sandwiches
= 5 u - 4 u
= 1 u
1 u = 45
Number of curry sandwiches
= 8 u
= 8 x 45
= 360
Answer(s): (a) 8 : 7 : 4 ; (b) 360
