Question
A vessel contains mixture in which 25% is water and
rest is milk. If 100 liters more water added in vessel, then quantity of water becomes 40% of mixture. Find the quantity of milk in the vessel?Solution
Let total mixture in vessel be Q liters.
Initial quantity of water in vessel = 0.25Q
And, quantity of milk in vessel = 0.75Q
(0.25Q + 100)/0.75Q = 40/60
15Q + 6000 = 30Q
15Q = 6000
Q = 400 l
Quantity of milk in vessel = 400 × 75/100 = 300 l
