Answer:
1.56 Days
Step-by-step explanation:
Peter can do a piece of work in 8 days
=> Peter 1 day Work = 1/8
Sam can do a piece of work in 10 days
=> Sam 1 day Work = 1/10
John can do a piece of work in 16 days
=> John 1 day Work = 1/16
Sam & john Worked for 4 Days
= 4 ( 1/10 + 1/16)
= 4 ( 8 + 5)/80
= 13/20
Work Left = 1 - 13/20 = 7/20
Sam & Peter 1 day work
1/8 + 1/10
= (5 + 4)/40
= 9/40
(7/20)/(9/40) = 14/9 = 1.56 Days
