Question

30 men take 10 days to build a wall. How many days will 25 men take?

Answer 1

30 men can build a wall in = 10 days

one man can build a wall in= 30×10

so, 25 men can build the same wall in= 30×10/25

= 30×2/5

= 6×2

= 12 days Answer.

Answer 2

Answer: 12 days

Step-by-step explanation:

• Given,30 men take 10 days to build a wall.
• 1 man will build the wall in=(30*10)days

                                                      =300 days

• So,time taken by 25 men to build the wall=$\frac{300}{25}$

                                                                                =12 days.

• Hence,time taken by 25 men to build the wall is 12 days.
