Question

A container is 4/5 full. When 10 L of milk is poured into it, the container become 9/10 full. What is the capacity of the container?W

Answer 1

Solution:

Let the capacity of container be 'x' litres.
Container of milk is 4/5 full=4x/5
Now, 10 l of milk is poured in container.
Therefore portion of container filled with milk=9x/10
As per given condition we have,

or, 4x/5+10=9x/10
or, 10=9x/10-4x/5
or, 10=(9x-8x)/10
or, 100=x

Capacity of the container = 100 litres.
