Question

If one third of 100 g of 27% aqueous sugar solution is taken in a
beaker and 10 g of sugar is added to it, the concentration of the
resulting solution will be (1) 48 34% (2) 44 38% (3) 34 84% (4) 43
84%

the initial solution has a mass of 100g
when 1/3rd o, f the solution is taken, the concentration will
remain same i e , (100/3)g of the solution has ((27*(100/3))/100)g
of sugar = 9g sugar in 33 33g solution
Now 10g sugar is added=> new concentration=(( (9+10)/(33 33+10))
*100)=43 8%
