A shopkeeper keeps his stock of rice flour in 50-kg bags. He has 4 such bags to be packed into smaller packets weighing 4 kg and 2 kg. He wants to have the same number of 4-kg packets and 2-kg packets.
- How many packets of rice flour does he pack altogether?
- How much rice flour is left over?
(a)
Total mass of rice flour
= 4 x 50
= 200 kg
Mass of one set of 1 2-kg packet and 1 4-kg packet
= 2 + 4
= 6 kg
Number of sets
= 200 ÷ 6
= 33 r 2
Number of packets of rice flour
= 2 x 33
= 66
(b)
Mass of rice flour left over = 2 kg
Answer(s): (a) 66; (b) 2 kg
