10 men working for 6 days can complete 5 copies of a book if there are 8 men working to complete 4 copies of the book how many days will it take

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

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
