Correct Answer: $2:3:3$


Solution : Given: The ratio of profit of S, T, and U = $1:2:3$
Let the capital of S, T, and U be $3x$, $4x$ and $6x$ respectively.
Let the time of investment of S, T, and U be $a$, $b$, and $c$ respectively.
$3ax:4bx:6cx = 1:2:3$
⇒ $\frac{3a}{4b}=\frac{1}{2}$ and $\frac{4b}{6c}=\frac{2}{3}$
⇒ $\frac{a}{b}=\frac{2}{3}$ and $\frac{b}{c}=\frac{1}{1}=\frac{3}{3}$
So, $a:b:c = 2:3:3$.
Hence, the correct answer is $2:3:3$
