Answer 1

Calculation of Repairs in the Workshops

To determine the difference in the number of irons repaired per day between the two workshops, we need to calculate the average number of irons repaired per day in each workshop.

In the first workshop, 45 irons were repaired in 5 days. To find the average number of irons repaired per day in the first workshop, we divide the total number of irons repaired (45) by the number of days (5):

Average number of irons repaired per day in the first workshop = 45 irons / 5 days = 9 irons per day.

In the second workshop, 21 irons were repaired in 3 days. To find the average number of irons repaired per day in the second workshop, we divide the total number of irons repaired (21) by the number of days (3):

Average number of irons repaired per day in the second workshop = 21 irons / 3 days = 7 irons per day.

Difference in Repairs per Day

To find the difference in the number of irons repaired per day between the two workshops, we subtract the average number of irons repaired per day in the second workshop from the average number of irons repaired per day in the first workshop:

Difference in repairs per day = Average number of irons repaired per day in the first workshop - Average number of irons repaired per day in the second workshop.

Substituting the values we calculated earlier:

Difference in repairs per day = 9 irons per day - 7 irons per day = 2 irons per day.

Therefore, the first workshop repaired 2 irons per day more than the second workshop.
