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 flour. How many packets of dried fruits were collected?
- The table shows the mass of each packet of food.
| Food Items |
Mass of each packet |
| Flour |
9 kg |
| Biscuits |
470 g |
| Dried Fruits |
350 g |
| Tea |
400 g |
What is the difference between the total mass of tea collected and the total mass of biscuits collected? Give your answer in kg.
(a)
Number of packets of flour collected = 1 u
1 u = 10
Total number of packets of food items collected
= 6 u
= 6 x 10
= 60
Number of packets of dried fruits collected
= 60 - 10 - 22 - 12
= 16
(b)
Total mass of tea collected
= 12 x 400
= 4800 g
Total mass of biscuits collected
= 22 x 470
= 10340 g
Difference in mass between the total mass of tea and the total mass of biscuits collected
= 10340 - 4800
= 5540 g
1000 g = 1 kg
5540 g = 5540 ÷ 1000 = 5.54 kg
Answer(s): (a) 16; (b) 5.54 kg
