Answer: 4 people take 27 minutes to paint 6 walls.
Step-by-step explanation:
Since we have given that
Number of people to paint 8 walls in 16 minutes = 9
We need to find the time taken by 4 people to paint 6 walls.
We will use "Time and Work " rule :
[tex]\dfrac{9\times 16}{8}=\dfrac{4\times x}{6}\\\\18=\dfrac{2}{3}\times x\\\\18\times \dfrac{3}{2}=x\\\\9\times 3=x\\\\27=x[/tex]
Hence, 4 people take 27 minutes to paint 6 walls.
