1 kg |
Lentils |

Milo |
405 g |
Biscuits |
200 g |
What is the difference between the total mass of biscuits collected and the total mass of lentils collected? Give your answer in kg.
(a)
Number of packets of rice collected = 1 u
1 u = 18
Total number of packets of food items collected
= 6 u
= 6 x 18
= 108
Number of packets of milo collected
= 108 - 18 - 38 - 24
= 28
(b)
Total mass of biscuits collected
= 24 x 200
= 4800 g
Total mass of lentils collected
= 38 x 365
= 13870 g
Difference in mass between the total mass of biscuits and the total mass of lentils collected
= 13870 - 4800
= 9070 g
1000 g = 1 kg
9070 g = 9070 ÷ 1000 = 9.07 kg
Answer(s): (a) 28; (b) 9.07 kg
