Question

if 5 men and 9 women can finish a piece of work in 19 days 3 men and 6 women will do the same in​

Answer 1

Step-by-step explanation:

5m×19=9w×19

5m=9w

M/9=w/5

9 and 5 are the wrkng speeds( man completes 9 pages per day suppose)

now total wrk = 5m×19=5(9)×19=45×19

3m+6w=[ 3(9)+6(5)]×no of days

=[27+30]×days

=57×days

Now equate both wrk i.e

57×days=45×19

Req. Days= 15 days
