There's even an easy method.

We know that,

Earlier, 30 men did a piece of work in 38 days.

After 25 days, (30 + 5) = 35 men can do the work in 12 days.

So, 35 men fan finish the remaining work in 12 days.

∴ 30 men can do it in...

$\frac{12 \times 35}{30} = 14$

Hence, 30 men can do a piece of work in 14 days, that is, the contractor would be one day behind.
