A bakery made some beef, egg and sardine sandwiches. For every 2 beef sandwiches that were made, 1 sardine sandwich were made. For every 5 beef sandwiches that were made, 4 egg sandwiches were made.
- Find the ratio of the number of beef sandwiches to egg sandwiches to sardine sandwiches made.
- After the bakery made another 95 sardine sandwiches, 25% of the sandwiches now were sardine sandwiches. How many beef sandwiches did the bakery make?
(a)

10 u |
8 u |
5 u |
Beef : Egg : Sardine
10 : 8 : 5
(b)

+ 95 |
After |
3x6 = 18 u |
1x6 = 6 u |
Total number of beef and egg sandwiches
= 8 u + 10 u
= 18 u
Increase in the number of sardine sandwiches
= 6 u - 5 u
= 1 u
1 u = 95
Number of beef sandwiches
= 10 u
= 10 x 95
= 950
Answer(s): (a) 10 : 8 : 5 ; (b) 950
