QA – Placement Quizzes | Ratio and Proportion | Question 8

Syrup and Water are mixed in 2:1 ratio to form 60 litres of a mixture. How much water needs to be added to make the ratio 1:2?
(A) 60 litres
(B) 85 litres
(C) 55 litres
(D) Cannot be determined


Answer: (A)

Explanation: Volume of Syrup in the mixture = 60 × 2/3 = 40 litres.
Volume of Water in the mixture = 60 × 1/3 = 20 litres
Let the required volume of water be x litres. Then,
40:(20+x) = 1:2
⇒ 20+x = 80
⇒ x = 60 litres.
