Answer 1

Answer:

Answer:

48 days

Step-by-step explanation:

piece of work done by A in one hour = 1/24

piece of work done by B in one hour = 1/16

piece of work done by A and B together in one hour= 1/24 +1/16

= 5/48

piece of work done by A ,B and C together in one hour = 1/8

piece of work done by C in one hour= 1/8 - 5/48

= 1/48

Days taken by C to complete the work = 1/(1/48)

= 48 days
