Noodles |
400 g |
What is the difference between the total mass of tea collected and the total mass of noodles collected? Give your answer in kg.
(a)
Number of packets of cereals collected= 1 u
1 u = 26
Total number of packets of food items collected
= 4 u
= 4 x 26
= 104
Number of packets of flour collected
= 104 - 22 - 26 - 32
= 24
(b)
Total mass of tea collected
= 22 x 365
= 8030 g
Total mass of noodles collected
= 32 x 400
= 12800 g
Difference between the total mass of tea and the total mass of noodles collected
= 12800 - 8030
= 4770 g
1000 g = 1 kg
4770 g = 4770 ÷ 1000 = 4.77 kg
Answer(s): (a) 24; (b) 4.77 kg
