    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 work
    A 38 days Correct Answer Incorrect Answer
    B 48 days Correct Answer Incorrect Answer
    C 36 days Correct Answer Incorrect Answer
    D 24 days Correct Answer Incorrect Answer

    Solution

    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
