12 men can dig a pond in 8 days.


12 men can dig a pond in 8 days. How many men can dig it in 6 days?


Let be the required number of men. Then, we have: 

No. of days 8 6
No. of men 12 x

Clearly, more men will require less number of days to dig the pond.

So, it is a case of inverse proportion.

Now, $8 \times 12=6 \times x$

$\Rightarrow x=\frac{8 \times 12}{6}$

$\Rightarrow x=16$

Therefore, 16 men can dig the pond in 6 days.
