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 \[\begin{align} & =\left[ 6\times x+6\left( x+\frac{x}{3} \right) \right]:\left[ 6\times 2x+6\left( 2x-\frac{2x}{2} \right) \right] \\ & :\left[ 6\times 3x+6\left( 3x+\frac{x}{3} \right) \right] \\ \end{align}\] = \[[6x+2x4x]:[12x+6x]:[18x+20x]\] \[=14x:18x:38x\] \[=7:9:19\]You need to login to perform this action.
