Answer 1

Answer:

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

i hope this is correct
