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.
