A shopkeeper keeps his stock of flour in 30-kg bags. He has 2 such bags to be packed into smaller packets weighing 2 kg and 7 kg. He wants to have the same number of 2-kg packets and 7-kg packets.
- How many packets of flour does he pack altogether?
- How much flour is left over?
(a)
Total mass of flour
= 2 x 30
= 60 kg
Mass of one set of 1 7-kg packet and 1 2-kg packet
= 7 + 2
= 9 kg
Number of sets
= 60 ÷ 9
= 6 r 6
Number of packets of flour
= 2 x 6
= 12
(b)
Mass of flour left over = 6 kg
Answer(s): (a) 12; (b) 6 kg
