Detailed Solution

We have to check if the final volume of water in each tank will be 75 liters.
Suppose the volume of water in the first tank is 2 x and the volume of water in the second tank is x .
As per the question:
2x25=x+25 Now rearranging the constants and variables:
2xx=25+25 x=50
So, the initial volume of the second tank will be 50.
Thus, the initial volume of the water in the first tank would have been:
2x=2×50=100
And, the final volume of water in each tank:
Tank 1= 100-25
=75 liters
Tank 2= 50+25
=75 liters
Hence, it can be concluded that the given statement is true.
Therefore, option 1 is correct.
