    Question

    P is 60% more efficient than Q. P takes 30 more days to

    finish a work as compared to the number of days taken by P and Q together to finish the same work. Find the time taken by Q to finish the same work alone.
    A 125days Correct Answer Incorrect Answer
    B 120days Correct Answer Incorrect Answer
    C 124.8days Correct Answer Incorrect Answer
    D 136.2days Correct Answer Incorrect Answer

    Solution

    Let efficiency of P = p and efficiency of Q = q p = 160% of q => p: q = 8: 5 Let time required by P and Q together to finish this job be “t”. (p + q) ×t = W => 13x × t = W    …. (1) ATQ- p × (t + 30) = W   => 8x × (t + 30) = W         … (2) By solving above two equations we get t = 48 13x × 48 = 5x × T   => T = 124.8 days
