Question
‘Pooja’ alone can finish a piece of work in 60 days.
After working for 36 days, she left the job. ‘Vikram’ then completed the rest in 12 days. How many days will Vikram take to complete 80% of the workSolution
ATQ,
Pooja’s work = 36/60 = 3/5
Remaining = 1 - 3/5 = 2/5
Vikram does 2/5 in 12 days
Full time for Vikram = 12 × (5/2) = 30 days
80% work = 0.8 × 30 = 24 days
