Correct Answer: 10

Solution : $\frac{M_1 D_1 H_1}{W_1} = \frac{M_2 D_2 H_2}{W_2}$
Where $M_1$ and $M_2$ are men, $H_1$ and $H_2$ are working hours per day, $D_1$ and $D_2$ are days, and $W_1$ and $W_2$ are work done
Given:
According to the question,
$ \frac{M_1 D_1 H_1}{W_1} = \frac{M_2 D_2 H_2}{W_2}$
$\Rightarrow \frac{10 imes 12 imes 7}{W} = \frac{14 imes D_2 imes 6}{W}$
$\Rightarrow D_2 =\frac{10 imes 12 imes 7}{14 imes 6}$
$ herefore D_2 = 10$
Hence, the correct answer is 10.
