Answer:
10 days
Step-by-step explanation:
We are given that
Each person takes 56 days
7 painters take time= painter days
In first 6 days , 7 painters take time=painter days
After 6 days , 28 volunteers are added then,
Total persons=28+7=35

Therefore, number of days are required before the painting of the king of rock 'n' roll is completed=days
Hence,10 more days are required before the painting of the king of rock 'n' roll is completed
