Question

20 tiles weigh 5kg. How much do 7 tiles weigh ? If a man wants to carry a weight of only 12kg , how many tiles will he be able to carry ?

Answer 1

Answer:

20tiles weigh = 5kg

so 1 tile weight is =5/20kg

=0.25 kg

then weight of 7tiles =7×0.25

=1.75kg

if a man want to carry a weight of only 12kg

then he will carry = 12/0.25 tiles

=48 tiles.

Answer 2

20 tiles→ 5kg (using unitary method)

1tile → 5/20kg

7tiles → 5/20 × 7 = 7/4kg

5kg→20tiles

1kg→4 tiles

12kg→48 tiles.
