Step-by-step explanation:

Let X be the initial number of men then,

According to the question,

5X = X + (X - 10) + (X - 20) + (X - 30) + (X - 40) + (X - 50)

⇒ 5X = 6X - 150

⇒ 6X - 5X = 150

⇒ X = 150 men

Answer 2

Given:

total work days$=5$

Solution:

Let X be the initial number of men then,

Know that, according to the question,

$\[\begin{array}{l}5X = X + \left( {X - 10} \right) + \left( {X - 20} \right) + \left( {X - 30} \right) + \left( {X - 40} \right) + \left( {X - 50} \right)\\ \Rightarrow 5X = 6X - 150\\ \Rightarrow 6X - 5X = 150\\ \Rightarrow X = 150\end{array}\]$  

Hence, the initial number of men is 150.
