# In How many Days can Complete the Same Work? If

If 4 men or 7 boys can do a work in 29 days than 12 men and 8 boys can complete the same work in how many days?

- 12 days
- 6 days
- 7 days
- 8 days

**Answer: (c) 7 days.
Explanation:-**

Work done by 4 men in a day = 1/29

Work done by 1 man in a day = 1/29 x 4

Work done by 7 boys in a day = 1/29

Work done by 1 boy in a day = 1/29 x 7

Work done by 12 men and 8 boys = 12/29 x 4 + 8/29 x 7

= 3/29 + 8/203

= 841/5887 = 1/7

Hence, 12 men and 8 boys can complete the same work in 7 days.
