    C 10 days Correct Answer Incorrect Answer
    D 18 days Correct Answer Incorrect Answer
    E 16 days Correct Answer Incorrect Answer

    Solution

    It is given, 8 men = 10 women (based on their efficiency) 10 women + 4 men = 10 women + 4 × (10/8) women = (10 + 5) women = 15 women So, w1 × t1 = w2 × t2 10 × 21 = 15 × t2 t2 = 14 days.
