    Answer:

    80 liters

    Step-by-step explanation:

    Let the amount of 60% solution be S60

    Let the amount of 30% solution be

    S30=40 litres

    Let the amount of 50% solution be

    S50=40+S60 litres

    So for this to balance we have:

    60 100

    S60

    +

    (

    30

    100

    =

    50

    100

    (

    +

    40

    )
