In a mixture of 80 litres of orange juice and soda, the amount of soda is 30 litres. How many litres of soda should be added to make the ratio of juice to soda 1 : 2?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 70 litres.
Mixture = 80 litres
Amount of soda = 30 litres
Amount of juice = 80 - 30 = 50 litres
Let soda added = x litres
50/(30 + x) = 1/2
⇒ 100 = 30 + x
⇒ x = 70 litres
