Answer 2

26 farmers plough the same field in 6 days if they work 10 hours a day.

Step-by-step explanation:

13 farmers can plough a field by working 8 hours a day in days = 15

1 farmer can plough a field by working 8 hours a day in days = $15 \times 13$

1 farmer can plough a field by working 1 hours a day in days = $15 \times 13 \times 8$

26 farmers can plough a field by working 1 hours a day in days = $\frac{15 \times 13 \times 8}{26}$

26 farmers can plough a field by working 10 hours a day in days = $\frac{15 \times 13 \times 8}{26 \times 10}$

26 farmers can plough a field by working 10 hours a day in days = $6$

Hence 26 farmers plough the same field in 6 days if they work 10 hours a day.
