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 coffee. 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 |
5 kg |
Coffee |
495 g |
Tea |
480 g |
Dried Fruits |
300 g |
What is the difference between the total mass of tea collected and the total mass of flour collected? Give your answer in kg.
(a)
Number of packets of coffee collected = 1 u
1 u = 38
Total number of packets of food items collected
= 3 u
= 3 x 38
= 114
Number of packets of dried fruits collected
= 114 - 36 - 38 - 22
= 18
(b)
1 kg = 1000 g
5 kg = 5 x 1000 = 5000
Total mass of flour collected
= 36 x 5000
= 180000 g
Total mass of tea collected
= 22 x 480
= 10560 g
Difference between the total mass of tea and the total mass of flour collected
= 180000 - 10560
= 169440 g
1000 g = 1 kg
169440 g = 169440 ÷ 1000 = 169.44 kg
Answer(s): (a) 18; (b) 169.44 kg
