Answer:
6 Days
Step-by-step explanation:
Work done by 1 man in 1 day is computed as:
= 1/(3*26) = 1 / 78
Work done by 1 woman in 1 day is computed as:
= 1/(5*26) = 1 / 130
Therefore work done by 7 men and 10 women in 1 day is computed here as:
= (7/78) + (10/130)
= 0.166667
Therefore, number of days required to complete the work is computed as:
= 1 / 0.166667
= 6 days
