A shopkeeper keeps his stock of flour in 60-kg bags. He has 5 such bags to be packed into smaller packets weighing 2 kg and 5 kg. He wants to have the same number of 2-kg packets and 5-kg packets.
- How many packets of flour does he pack altogether?
- How much flour is left over?
(a)
Total mass of flour
= 5 x 60
= 300 kg
Mass of one set of 1 5-kg packet and 1 2-kg packet
= 5 + 2
= 7 kg
Number of sets
= 300 ÷ 7
= 42 r 6
Number of packets of flour
= 2 x 42
= 84
(b)
Mass of flour left over = 6 kg
Answer(s): (a) 84; (b) 6 kg
