A shopkeeper keeps his stock of rice flour in 50-kg bags. He has 2 such bags to be packed into smaller packets weighing 3 kg and 5 kg. He wants to have the same number of 3-kg packets and 5-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
= 2 x 50
= 100 kg
Mass of one set of 1 5-kg packet and 1 3-kg packet
= 5 + 3
= 8 kg
Number of sets
= 100 ÷ 8
= 12 r 4
Number of packets of rice flour
= 2 x 12
= 24
(b)
Mass of rice flour left over = 4 kg
Answer(s): (a) 24; (b) 4 kg
