The bar graph shows the number of packets of different food collected in a donation drive.
- 16 of the total number of packets of food collected was milo. How many packets of dried fruits were collected?
- The table shows the mass of each packet of food.
Food Items |
Mass of each packet |
Rice |
6 kg |
Milo |
440 g |
Pasta |
345 g |
Dried Fruits |
200 g |
What is the difference between the total mass of pasta collected and the total mass of rice collected? Give your answer in kg.
(a)
Number of packets of milo collected = 1 u
1 u = 12
Total number of packets of food items collected
= 6 u
= 6 x 12
= 72
Number of packets of dried fruits collected
= 72 - 14 - 12 - 30
= 16
(b)
1 kg = 1000 g
6 kg = 6 x 1000 = 6000
Total mass of rice collected
= 14 x 6000
= 84000 g
Total mass of pasta collected
= 30 x 345
= 10350 g
Difference between the total mass of pasta and the total mass of rice collected
= 84000 - 10350
= 73650 g
1000 g = 1 kg
73650 g = 73650 ÷ 1000 = 73.65 kg
Answer(s): (a) 16; (b) 73.65 kg
