A shopkeeper keeps his stock of rice flour in 35-kg bags. He has 4 such bags to be packed into smaller packets weighing 6 kg and 3 kg. He wants to have the same number of 6-kg packets and 3-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 35
= 140 kg
Mass of one set of 1 3-kg packet and 1 6-kg packet
= 3 + 6
= 9 kg
Number of sets
= 140 ÷ 9
= 15 r 5
Number of packets of rice flour
= 2 x 15
= 30
(b)
Mass of rice flour left over = 5 kg
Answer(s): (a) 30; (b) 5 kg
