4 days

Explanation:

Given - Ram and Hari can finish a piece of work in 6 days and 12 days

respectively.

To find - In how many days will they finish it working together

Proof -

As given,

Ram and Hari can finish a piece of work in 6 days and 12 days respectively.

⇒1 day work of Ram done in = $\frac{1}{6}$

1 day work of Hari done in = $\frac{1}{12}$

If they work together,

1 day work of both together done in = $\frac{1}{6}$ + $\frac{1}{12}$ = $\frac{2 + 1}{12} = \frac{3}{12}$ = $\frac{1}{4}$

As we know Work is inversely proportional to efficiency

And efficiency = Person's 1 day work

As we have ,

1 day work of both together done in = $\frac{1}{4}$

⇒ Total work done in 4 days if they work together.
