- 14 of the total number of packets of food collected was rice. How many packets of coffee were collected?
- The table shows the mass of each packet of food.
| Food Items |

| Rice |
1 kg |
| Dried Fruits |
475 g |
| Coffee |
455 g |
| Pasta |
200 g |
What is the difference between the total mass of pasta collected and the total mass of dried fruits collected? Give your answer in kg.
(a)
Number of packets of rice collected = 1 u
1 u = 26
Total number of packets of food items collected
= 4 u
= 4 x 26
= 104
Number of packets of coffee collected
= 104 - 26 - 32 - 16
= 30
(b)
Total mass of pasta collected
= 16 x 200
= 3200 g
Total mass of dried fruits collected
= 32 x 475
= 15200 g
Difference in mass between the total mass of pasta and the total mass of dried fruits collected
= 15200 - 3200
= 12000 g
1000 g = 1 kg
12000 g = 12000 ÷ 1000 = 12 kg
Answer(s): (a) 30; (b) 12 kg
