Answer:
10 days
Step-by-step explanation:
We are given that
Each person takes 56 days
7 painters take time=[tex]56\times 7=392[/tex] painter days
In first 6 days , 7 painters take time=[tex]7\times 6=42[/tex]painter days
After 6 days , 28 volunteers are added then,
Total persons=28+7=35
Now, remaining days=392-42=350
Therefore, number of days are required before the painting of the king of rock 'n' roll is completed=[tex]\frac{350}{35}=10[/tex]days
Hence,10 more days are required before the painting of the king of rock 'n' roll is completed
