Question

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

Answer 1

5m *19=9w*19
5m =9w
Therefore m---9
W---5
Put these in any one equation whether left side or right side. Suppose we take w for total..
9w*19
9*5*19= total work - - - - 855
Now these total work do by3m+6w
Put value of m nd w that we calculate in above step m---9,w---5
Then 3*9+6*5
27+30=57
Time taken =855/57=15days
