Calculation of the Number of Days Off for Each Seamstress

To calculate the number of days off for each seamstress in a month with 30 days, we need to consider the following information:

- There are 108 seamstresses working in the sewing workshop. - 25% of all 120 sewing machines are sent for daily repairs.

Let's break down the calculation step by step:

1. Calculate the number of sewing machines sent for daily repairs: - 25% of 120 sewing machines = 0.25 * 120 = 30 sewing machines.

2. Calculate the number of working sewing machines: - Total sewing machines - Sewing machines sent for repairs = 120 - 30 = 90 sewing machines.

3. Calculate the number of sewing machines per seamstress: - Number of working sewing machines / Number of seamstresses = 90 / 108 ≈ 0.833 sewing machines per seamstress.

Now, let's calculate the number of days off for each seamstress:

A) 5 days off: - Since each seamstress has approximately 0.833 sewing machines, it means that some seamstresses may have 1 sewing machine while others may have 0. - If a seamstress has 0 sewing machines, it means she doesn't have any work to do and can take a day off. - If a seamstress has 1 sewing machine, it means she has work and cannot take a day off. - Therefore, the number of seamstresses who can take a day off depends on the number of seamstresses with 0 sewing machines.

B) 4 days off: - Similar to option A, some seamstresses may have 0 sewing machines, allowing them to take a day off. - However, there may be fewer seamstresses with 0 sewing machines compared to option A, resulting in fewer days off.

C) 3 days off: - Similar to options A and B, some seamstresses may have 0 sewing machines, allowing them to take a day off. - However, there may be even fewer seamstresses with 0 sewing machines compared to options A and B, resulting in fewer days off.

D) 7 days off: - This option is not mentioned in the given question and cannot be determined based on the provided information.

E) 2 days off: - Similar to options A, B, and C, some seamstresses may have 0 sewing machines, allowing them to take a day off. - However, there may be even fewer seamstresses with 0 sewing machines compared to options A, B, and C, resulting in fewer days off.

Based on the information provided, the correct answer would be option A) 5 days off since it allows for the maximum number of seamstresses to have a day off.

Please note that the exact number of days off for each option cannot be determined without additional information about the distribution of sewing machines among the seamstresses.
