Answer 2

Answer:

6 Days.

Step-by-step explanation:

If 3 men or 5 women can do the work in 26 days .

then efficiency of 3 men and 5 women are equal.

therefore, 3 men = 5 women.

w= 3/5 m

10w = 3x10/5 M

10w = 6M

now,

7M + 10W = 7M + 6M (as 10w=6M)

=13M

If 3 men = 26 days

as the number of men increases, days decreases, it is inversely proportional .

so, 1 men = 26 x 3 = 78  days.

13 men = 78/13 = 6 days.

Hence , it will take 6 days
