According to the question,

✧ Using unitary method in the question,

⚘ Here, engineer pumps out 350 litre of water per hours .

350 litre of water = 1 hour .

➝1 liter of water out = $\{1}{350}$

➝Then, 12950 liters of water out in =

$\dfrac{1}{350}$ × 12950

➝ $\dfrac{1}{350}$ × 12950

➝ $\dfrac{12950}{350}$

➝ $\cancel{\dfrac{12950}{350}}$

➝ 37 hrs

➡Therefore, 12950 liters of water out in 37 hours.
