    (A+B+C)=7/2=3.5

Time and Work Type 3

  • Now Find Out Individual Efficiency: We Know A+B=3 & A+B+C=3.5 SO By Putting Value We Can Find Out Value Of C=0.5
  • C Can Do 0.5 Works In A Day. How Many Days He Will Take To Do 60 Works?
  • 60/0.5=120 Days
  • By This Method We Can Find Work Done By A And B. Please Answer In Comment Box.
