What is the difference between the total mass of lentils collected and the total mass of pasta collected? Give your answer in kg.
(a)
Number of packets of dried fruits collected= 1 u
1 u = 36
Total number of packets of food items collected
= 3 u
= 3 x 36
= 108
Number of packets of flour collected
= 108 - 12 - 36 - 32
= 28
(b)
Total mass of lentils collected
= 12 x 390
= 4680 g
Total mass of pasta collected
= 32 x 200
= 6400 g
Difference between the total mass of lentils and the total mass of pasta collected
= 6400 - 4680
= 1720 g
1000 g = 1 kg
1720 g = 1720 ÷ 1000 = 1.72 kg
Answer(s): (a) 28; (b) 1.72 kg
