Answer 2

Problem Analysis

We are given that in a workshop, 120 bed sacks were sewn in 6 days, with the same number of sacks sewn each day. We need to determine how many days it will take to sew 100 bed sacks if 5 more sacks are sewn each day.

Solution

To solve this problem, we can set up a proportion based on the given information. Let's denote the number of sacks sewn each day as x.

According to the given information, we have the following proportion:

120 sacks / 6 days = 100 sacks / (6 + y) days

where y represents the additional number of sacks sewn each day.

To solve for y, we can cross-multiply and solve for y:

120 * (6 + y) = 100 * 6

Simplifying the equation:

720 + 120y = 600

120y = 600 - 720

120y = -120

y = -120 / 120

y = -1

Since the number of sacks sewn each day cannot be negative, we can conclude that it is not possible to sew 100 bed sacks if 5 more sacks are sewn each day.
