    Ravi and Ramesh can do a job together in 20 days. They

    worked together for 12 days and then Suresh finished the remaining work alone in 10 days.Find how long Suresh alone will take to complete 90% of the total job.
    A 22.5 Correct Answer Incorrect Answer
    B 32.5 Correct Answer Incorrect Answer
    C 62.5 Correct Answer Incorrect Answer
    D 28.4 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    Fraction of work done by Ravi and Ramesh = 12 / 20 = 3/5

    Fraction of work done by Suresh = 1 - 3/5 = 2/5

    So, number of days taken by Suresh alone to complete the entire work = 10 ÷ (2/5) = 25 days

    So, time taken by Suresh to complete 90% of the work = 25 × 0.90 = 22.5 days
