The ratio of the quantities of acid and water in a mixture is 1 : 3. If 5 liters of acid is further added to the mixture, the new ratio becomes 1 : 2. The quantity of new mixture in liters is?
Answer & explanation
Correct answer: option 4
A : W
old 1 : 3 ..........(i)
New 1 : 2 ..........(ii)
(i) × 2 and (ii) × 3 to make the quantity of water equal,
A : W
old 2 : 6
New 3 : 6
Difference of Acid in old and new ⇒ 1R = 5 (given)
Thus, Quantity of new mixture ⇒ 9R = 9 × 5 = 45
