54 men working 8 hours per day dig 30 m deep.

54 men working 8 hours per day dig 30 m deep. How many extra men should be put to dig to a depth of 50 m working 6 hours per day?

Answer/Solution

C)66

Steps/Work

(54 * 8)/30
= (x * 6)/50
=> x =120
120 – 54
= 66

men working hours per day dig m deep. How many extra men should be put to dig to a depth of m working hours per day?

Calculated Answer

66

Step by Step Solution

In order to solve problem, you must evaluate (n₃ * (n₀ * n₁) / n₂) / n₄ - n₀.

n₀ =	54
n₁ =	8
n₂ =	30
n₃ =	50
n₄ =	6

(n₃ * (n₀ * n₁) / n₂) / n₄ - n₀
Evaluate n₀ * n₁ = 432
(n₃ * 432 / n₂) / n₄ - n₀
Evaluate 432 / n₂ = 14.4
(n₃ * 14.4) / n₄ - n₀
Evaluate n₃ * 14.4 = 720
720 / n₄ - n₀
Evaluate 720 / n₄ = 120
120 - n₀
Evaluate 120 - n₀ = 66
66
The answer to the problem and the result of (n₃ * (n₀ * n₁) / n₂) / n₄ - n₀ is 66
