    A, B and C started a business with their investments in the ratio of 1 : 2 : 3. After 6 months A invested one-third more as before and B withdrew half of his investment while C invested one-third more as before. Find the ratio of their profits at the end of the year.

    A)  11 : 23 : 37                

    B)  13 : 21 : 33

    C)  7 : 9 : 19        

    D)       14 : 21 : 38

    E)  12 : 26 : 31

    Correct Answer: C

    Solution :

    Let A, B and C invest the amounts x, 2x and 3x respectively. Ratio of their profits at the end of the year \[\begin{align}   & =\left[ 6\times x+6\left( x+\frac{x}{3} \right) \right]:\left[ 6\times 2x+6\left( 2x-\frac{2x}{2} \right) \right] \\  & :\left[ 6\times 3x+6\left( 3x+\frac{x}{3} \right) \right] \\ \end{align}\] =  \[[6x+2x4x]:[12x+6x]:[18x+20x]\] \[=14x:18x:38x\] \[=7:9:19\]
