# In How Many Days 6 Men and 12 Women Can Do the Same Piece of Work? If

If 4 men or 8 women can do a piece of work in 15 days, in how many days can 6 men and 12 women do the same piece of work?

- 45 days
- 5 days
- 30 days
- 20 days

**Answer: (2) 5 days**

**Explanation:-
**4 men = 8 women

Then, 1 man = 2 women

4 man can do a work = 15 days

Formula-

M1D1 = M2D2

Where, M = number of men & D = Number of days

Then, M1 = 4 , D1 = 15 , M2 = (6 + 6) = 12 , D2 =?

Then, 4 x 15 = 12 X ?

? = 60 /12

? = 5 days

Then, 5 days can 6 men and 12 women do the same piece of work.

Hence, the answer is (2) 5 days.
