Answer 1

Answer:

As we know that 5 men and 9 women do the work in 19 days.

so,5men=9women

1men=9/5women

3men =3×9/5=27/5women

number of persons doing the work =3men and 6 women

=》27/5women+6women=》57/5women

Let x be the days required to complete the work

As we kknow that more women will take less time to complete the work

therefore,9:57/5::x:19

9×19=57/5×x

x=5×19×9/57

x=15

so,they took 15 days to complete the same work.

Answer 2

Step-by-step explanation:

9 women = 5 men

Women = 5/9 men

Again,

3 men + 6 women

= 3+ 6* 5/9 men

= 19/3 men

let X days required

According to the question

19 *5 = X* 19/3

X = 15 days
