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?

Answer 1

Let the capacity of container be 'x' l
container of milk is 4/5 full=4x/5
10 l of milk is poured in container.
Therefore portion of container filled with milk=9x/10
As per given condition we have,
4x/5+10=9x/10
10=9x/10-4x/5
10=(9x-8x)/10
100=x
Hence capacity of container is of 100 l.
