Let time taken by B = x
Then, time taken by A = 2x
and time taken by C = 3x
According to the question.
\( \Large \frac{1}{x}+\frac{1}{2x}+\frac{1}{3x}=\frac{1}{12} \)
=> \( \Large 1+\frac{1}{2}+\frac{1}{3}=\frac{x}{12} \)
=> \( \Large \frac{6+3+2}{6}=\frac{x}{12} \)
=> 11= \( \Large \frac{x}{2} \)
x=22
Required number of days
= 2x = \( \Large 2\times 22 \)=44days
