    'Ramesh' can complete a work in 40 days. He started the

    work and left after 24 days from starting. The remaining work was done by 'Suresh' in 30 days. Find the time taken by 'Suresh' to complete 75% of the work.
    A 25 days Correct Answer Incorrect Answer
    B 17.5 days Correct Answer Incorrect Answer
    C 21.6 days Correct Answer Incorrect Answer
    D 56.25 days Correct Answer Incorrect Answer

    Solution

    ATQ,

    Fraction of work completed by 'Ramesh' = (24/40) = (3/5)

    Remaining work = 1 - (3/5) = (2/5)

    Time taken by 'Suresh' to complete (2/5)th of the work = 30 days

    Time taken by 'Suresh' to complete the whole work = 30 × (5/2) = 75 days

    Therefore, time taken by 'Suresh' to complete 75% of the work = 0.75 × 75 = 56.25 days
