8 kg |
Lentils |

Dried Fruits |
395 g |
Milo |
200 g |
What is the difference between the total mass of milo collected and the total mass of lentils collected? Give your answer in kg.
(a)
Number of packets of rice collected = 1 u
1 u = 40
Total number of packets of food items collected
= 3 u
= 3 x 40
= 120
Number of packets of dried fruits collected
= 120 - 40 - 26 - 36
= 18
(b)
Total mass of milo collected
= 36 x 200
= 7200 g
Total mass of lentils collected
= 26 x 360
= 9360 g
Difference in mass between the total mass of milo and the total mass of lentils collected
= 9360 - 7200
= 2160 g
1000 g = 1 kg
2160 g = 2160 ÷ 1000 = 2.16 kg
Answer(s): (a) 18; (b) 2.16 kg
