Initially in the 10L solution there is 1.5L sugar and 8.5L water. We know that:- Final volume of sugar = Initial volume of sugar × (Volume of solution that is not drawn out/total volume of solution)‌n i.e 1=1.5×(
10−x
10
)2 Where x is the volume of the solution drawn out. Thus, 200=3×(102−20x+x2) Solving we get x≈1.873 The closest value in the option is option D. Thus, option D is the correct answer.
