Let the work done by 1 painter in a day x
Then, work done by 4 painters in a day is 4x
Total work done by painters = 4x × 6
= 24x
Now, according to question only 3 painters are working.
So, Time taken by 3 painters to complete the work = 24x/3x
= 8
Hence, it will take 8 days to complete the work for 3 painters.
