In a 160 litre mixture of milk and water ,%of water is only 30%.
the milkman gave 40 litres of this mixture to a customer and then added some litres of water to remaining mixture.
as a result the percentage of water in the final mixture became 44%.
what was the quantity of water added by the milkman ?(in litres)
:
let x = amt of water added to do this
A mixture equation using the decimal equiv of percent water
.30(40) + x = .44(x+40)
12 + x = .44x + 17.6
x - .44x = 17.6 - 12
.56x = 5.6
x = 5.6/.56
x = 10 liters of water added
