Question

A pile of sand has a weight of 60 kg

The sand is put into a small bag, a medium bag and a large bag in the ratio 2:3:7
Work out the weight of the sand in each bag

Answer 1

Small bag = 2x

Medium bag = 3x

Large bag = 7x

2x + 3x + 7x = 60

12x = 60

x = 60/12

x = 5

Small bag = 2(5) = 10 kg

Medium bag = 3(5) = 15 kg

Large bag = 7(5) = 35 kg

Done.
