Solution

The correct option is A 10
Volume of solute (ethyl alcohol) = 50 mL
Volume of solvent (water) = 450 mL
Total volume of solution = 50 + 450 = 500 mL
Volume by volume percentage $= \frac{v o l u m e o f s o l u t e}{v o l u m e o f s o l u t i o n} \times 100$
$= \frac{50}{500} \times 100 = 10 %$
