A mixture of 125 gallons of wine and water contains 20% wine. How much wine must be added to mixture in order to increase the percentage of wine to 25% of the new mixture ?
Answer & explanation
Correct answer: option 3
Quantity of wine inthe mixture = 125 x \(\frac{20}{100}\) = 25
Let the quantity of wine to be added be x,
Then the quantity of water reduces to 75%
100 gallons of water = 75% of total mixture
total mixture = 133.33 gallons
We need to mix,
133.33 - 125 = 8.33 gallons of wine
