The Correct Option is A
Solution and Explanation
Given that the Mixture of tonic and water contain:
Tonic = 30l
Water = 10l
Now, quantity of water = 10 + x (let x be added)
10 + x = \(\frac{1}{3}\) × (40 + x)
By simplifying the equation, we get
x = 5 litres.
The correct option is (A)
Tonic = 30l
Water = 10l
Now, quantity of water = 10 + x (let x be added)
10 + x = \(\frac{1}{3}\) × (40 + x)
By simplifying the equation, we get
x = 5 litres.
The correct option is (A)
