3 kg |
Dried Fruits |

Coffee |
410 g |
Pasta |
400 g |
What is the difference between the total mass of dried fruits collected and the total mass of pasta collected? Give your answer in kg.
(a)
Number of packets of coffee collected= 1 u
1 u = 24
Total number of packets of food items collected
= 5 u
= 5 x 24
= 120
Number of packets of flour collected
= 120 - 36 - 24 - 38
= 22
(b)
Total mass of dried fruits collected
= 36 x 260
= 9360 g
Total mass of pasta collected
= 38 x 400
= 15200 g
Difference between the total mass of dried fruits and the total mass of pasta collected
= 15200 - 9360
= 5840 g
1000 g = 1 kg
5840 g = 5840 ÷ 1000 = 5.84 kg
Answer(s): (a) 22; (b) 5.84 kg
