    Question

    ‘Neha’ can complete a task in 90 days. She worked for

    54 days and then left. The rest of the task was completed by ‘Karan’ in 24 days. How much time would Karan take to finish 80% of the task?
    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,

    Neha’s work = 54/90 = 3/5

    Remaining = 1 - 3/5 = 2/5

    Karan does 2/5 in 24 days

    Full work time for Karan = 24 × (5/2) = 60 days

    80% work = 0.8 × 60 = 48 days
