    200 g of sugar solution has 40% sugar in it. How much sugar should be added to make it 50% in the solution?

    A) 10 g                             

    B) 40 g

    C) 60 g                             

    D) 80 g

    Correct Answer: B

    Solution :

    According to the question,
    Amount of sugar in 200 g sugar solution
                            \[=200\times \frac{40}{100}=80\,g\]
    Now,     \[\frac{80+x}{200+x}=\frac{50}{100}\]
    \[\Rightarrow \]   \[160+2x=200+x\]\[\Rightarrow \]\[x=40\,g\]
