Question
The volume of water in a tank is twice of that in the other. If we draw out 25 litres from the first and add it to the other, the volumes of the water in each tank will be the same. Find the volume of water in each tank.
Solution
Let ‘x’ be the volume of water in the second tank.
The volume of water in the first tank be 2x.
According to the question
⇒ 2x – 25 = x + 25
⇒ 2x – x = 25 + 25
∴ x = 50
The volume of water in the second tank is 50 litres.
Volume of water in the first tank = 2x
= 2 × 50
= 100
Therefore, the volume of water in the first tank is 100 litres.
