A bakery made some mushroom, curry and chocolate sandwiches. For every 2 mushroom sandwiches that were made, 1 chocolate sandwich were made. For every 5 mushroom sandwiches that were made, 4 curry sandwiches were made.
- Find the ratio of the number of mushroom sandwiches to curry sandwiches to chocolate sandwiches made.
- After the bakery made another 90 chocolate sandwiches, 25% of the sandwiches now were chocolate sandwiches. How many mushroom sandwiches did the bakery make?
(a)
Mushroom |
Curry |
Chocolate |
2x5 |
|
1x5 |
5x2 |
4x2 |
|
10 u |
8 u |
5 u |
Mushroom : Curry : Chocolate
10 : 8 : 5
(b)
|
Mushroom |
Curry |
Chocolate |
Before |
18 u |
5 u |
Change |
No change |
+ 90 |
After |
3x6 = 18 u |
1x6 = 6 u |
Total number of mushroom and curry sandwiches
= 8 u + 10 u
= 18 u
Increase in the number of chocolate sandwiches
= 6 u - 5 u
= 1 u
1 u = 90
Number of mushroom sandwiches
= 10 u
= 10 x 90
= 900
Answer(s): (a) 10 : 8 : 5 ; (b) 900
