Correct Answer - B
`n_(A)=6 " mas of "A = 6xx20 =120 g`
`n_(B)=4 " mas of "B = 4xx25 =100 g`
`100 g " of "B = 220 g ` of solution
50 g of B = 110 g of solution

In an aqueous solution of urea, mole fraction of urea is 0.4. Then w/w% of urea is:

Mole fraction of urea =0.4 0.4 moles of urea +0.6 moles of `H_(2)O` `%(w//w)=(0.4xx60)/((0.4xx60)+(0.6xx18))=(24)/(24+10.8)xx100` `=(24)/(34.8)xx100=69%`
