Question

A bucket can hold 20litres of water.It's 3/5 parts is filled with water.what is the amount of water required to fill the bucket completely?

Answer 1

3/5 the part of 20 lites =20×3/5
which is 12 lites
amount of bucket filled=12 lites
amount required to fill the bucket=20-12
which is 8 litres

Answer 2

Total amount of water that bucket can hold=20L
Amount of water in bucket =3/5
Amount of water required to fill bucket=?
Then, 20-3/5
=LCM=5
=100/5-3/5
=97/5
Hence, we will need 97/5 to fill the required bucket.
