Hey there !
Let x be the number of days to be taken to work by 9 workers to build a wall
Given that -
24 workers can build a wall in 15 days
so 1 worker in one day will work = 24 × 15
given that 9 worker in x days so
Hence 9 workers will take 40 days to build a wall
Hope this would help you !

Hi dear!
We know that,
24 workers can build a wall in 15 days.
Hence,
1 worker will take 360 days(by multiplying 24 by 15) to build that wall.
Now,
We have to find,
How much will 9 workers take to build a similar wall.
Well of course 9 workers will take more time than 24 workers.
Now let's find our final answer,
To find the time taken by 9 workers to build the wall,
We will have to divide the time taken by 1 worker to do the work(i.e. to build the wall) by the number of workers whose time taken to complete the work is to be found.
So,
Hence,
9 workers will take 40 days to build a similar wall.
Thanks for the question! (^_^)
