Question

if 5 men or 9 women can do a piece of work in 19 days 3 men and 16 women will do the same work in how many days​

Answer 1

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
