Answer 1

Step-by-step explanation:

this is urs answer ......... .....

Answer 2

ANSWER

It is given that 5 men or 9 women can do the job in 19 days.

So, 5 men=9 women

1 man = 59 women

3 men = 3 ( 59 ) women

So, work done = 3 men+6 women = 3 ( 59)+6

= 527+6

= 557

Now,

W

M 1

D 1 = W 2

M 2

D 2

let D 2

=xW

19∗19 = W

2557 ∗x

⟹9∗19= 5

57x⟹3= 5x

⟹x=15 days

So, option (b) is correct.
