Question

3/5 part of a keg is full and 180 liters of oil is needed to fill it, so what is the capacity of the casks?​

Answer 1

Answer:

3/5 part is full.

So 1-(3/5) =2/5 part is empty.

To fill this empty part 180L is needed

2/5 part = 180

1 (full) = 180×(5/2) = 450L

Answer 2

Step-by-step explanation:

Given:-

3/5 part of a keg is full and 180 liters of oil is needed to fill it.

To find:-

what is the capacity of the casks?

Solution:-

Let the capacity of a keg be X litres

Oli filled parts=3/5 of X=3X/5

Amount of Oil is needed=180 litres

now we can written as

=>(3X/5)+180=X

=>(3X+900)/5=X

=>3X+900=5X

=>5X-3X=900

=>2X=900

=>X=900/2

=>X=450

Answer:-

The capacity of the keg =450 litres
