A 30 L solution has sugar and water in the ratio 4 : 1. How much water should be added to make the ratio 1 : 1?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 18 L.
Sugar = (4/5) × 30 = 24 L
Water = (1/5) × 30 = 6 L
Let x L water be added.
Then new ratio sugar : water = 24 : (6 + x) = 1 : 1
24 = 6 + x
x = 18
