<gadget id="calculator">45*5/100</gadget>
<output>9/4 = around 2.25</output>
2.25litres   Let X litres of water is added to the solution, then there is 2.25litres of acid in (5+ X ) Litres of liquid.   25% of ( 5 + X )= 2.25, 25/100* ( 5 + X ) = 2.25   X = 225-125/25 = 4   ANSWER:4.5litres
<result>D</result>
