(i) Given : 2 women and 5 men finish a work in 4 days.

Now, Work done by them in 1 - day:

⇒ 2W + 5M = (1/4)  

⇒ 4(2W + 5M) = 1

⇒ 8W + 20M = 1 ----- (1)


(ii) Given : 3 women and 6 men finish a work in 3 days.

Now, Work done by them in 1 - day:

⇒ 3W + 6M = (1/3)

⇒ 3(3W + 6M) = 1

⇒ 9W + 18M = 1    ------ (2)


On solving (1) * 9 & (2) * 8, we get

⇒ 72W + 180M = 9

⇒ 72W + 144M = 8

   --------------------------

                 36M = 1

                     M = (1/36).


Substitute M = (1/36) in above equations, we get

⇒ 72M + 180M = 9

⇒ 72M + 180(1/36) = 9

⇒ 72M + 5 = 9

⇒ 72M = 4

⇒ M = 1/18.


Therefore,

Total Time taken by men to finish the work = 36 days.

Total Time taken by women to finish the work = 18 days.



Hope it helps!
