Answer:
The number of days required for 8 men working to complete 4 copies of the books is 6 days
Step-by-step explanation:
Given As
The number of men (M1) = 10
The number of working days (D1) = 6 days
The work done (W1) = 5 copies
Again,
The number of men (M2) = 8
The number of working days (D2) = D2 days
The work done (W2) = 4 copies
∵ = constant
So ,
or,
Or, =
Or, D2 =
∴ D2 = 6 days
Hence The number of days required for 8 men working to complete 4 copies of the books is 6 days Answer

The first step for solving this equation is to determine the defined range.
, x ≠ 1
Remember that when the denominators of both fractions are the same,, you need to set the numerators equal. This will look like the following:
= 5
Take the root of both sides of the equation and remember to use both positive and negative roots.
x +/-![\sqrt[4]{5}](https://tex.z-dn.net/?f=%20%5Csqrt%5B4%5D%7B5%7D)
Separate the solutions.
x = , x ≠ 1
x = -
Check if the solution is in the defined range.
x =
x = -
This means that the final solution to your question are the following:
x =
x = -
