# 50 workers can build 50 walls in 25 days how many days will it take for 25 workers to build 25 walls

24 workers can build a wall in 15 days. How many days will 9 workers take to build a similar wall?

Number of days taken by 24 workers to build a wall = 15 days

Number of days taken by 1 worker to build the wall = 15 × 24 = 360 days (less worker means more days)

Number of days taken by 9 workers to build the wall = `360/9` = 40 days

40 men can finish a piece of work in 26 days. How many men will be needed to finish it in 16 days?

Number of men required to complete the work in 26 days = 40

Number of men required to complete the work in 1 day = 40 × 26 = 1040 men (less men more days)

Number of men required to complete the work in 16 days = `1040/16` = 65
