Answer:

R.E.F image

A→ 20 days

B→ 15 days

Let us say. 60 unit work was there & C = x unit/Day.

A = 3 unit/Day

B=4 unit /Day.

A+B = 7×6=42 unit work  done by A & B. left

(60-42) unit = 10 unit will be done by A&C

A+C=(3+x)×4=10⇒12+4x=10⇒x=46=2.5dayunit.

C Alone could do the work.

= 1.5unit/day6.0unit

= 40 day
