A bakery made some egg, sardine and lotus paste sandwiches. For every 2 egg sandwiches that were made, 1 lotus paste sandwich were made. For every 5 egg sandwiches that were made, 4 sardine sandwiches were made.
- Find the ratio of the number of egg sandwiches to sardine sandwiches to lotus paste sandwiches made.
- After the bakery made another 61 lotus paste sandwiches, 25% of the sandwiches now were lotus paste sandwiches. How many egg sandwiches did the bakery make?
(a)

Egg : Sardine : Lotus Paste
10 : 8 : 5
(b)

+ 61 |
After |
3x6 = 18 u |
1x6 = 6 u |
Total number of egg and sardine sandwiches
= 8 u + 10 u
= 18 u
Increase in the number of lotus paste sandwiches
= 6 u - 5 u
= 1 u
1 u = 61
Number of egg sandwiches
= 10 u
= 10 x 61
= 610
Answer(s): (a) 10 : 8 : 5 ; (b) 610
