The bar graph shows the number of packets of different food collected in a donation drive.
- 13 of the total number of packets of food collected was rice. How many packets of dried nuts were collected?
- The table shows the mass of each packet of food.
| Food Items |
Mass of each packet |
| Rice |
9 kg |
| Dried Fruits |
355 g |
| Dried Nuts |
260 g |
| Milo |
400 g |
What is the difference between the total mass of milo 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 = 28
Total number of packets of food items collected
= 3 u
= 3 x 28
= 84
Number of packets of dried nuts collected
= 84 - 28 - 24 - 18
= 14
(b)
Total mass of milo collected
= 18 x 400
= 7200 g
Total mass of dried fruits collected
= 24 x 355
= 8520 g
Difference in mass between the total mass of milo and the total mass of dried fruits collected
= 8520 - 7200
= 1320 g
1000 g = 1 kg
1320 g = 1320 ÷ 1000 = 1.32 kg
Answer(s): (a) 14; (b) 1.32 kg
