Question
Rahul does half the work done by Karan in 2/3 of the time.
If they together can complete the work in 14 days, how much time will Karan take to complete the work?Solution
Let time taken by Karan to complete the work = t days
Rahul takes 2 × (2t/3) = 4t/3 days.
Efficiency of Karan = 1/t,
Efficiency of Rahul = 3/4t.
Total efficiency = 1/t + 3/4t = 1/14
Solving for t, we get t = 24.5 days.
