    Explanation:
    Let total work is LCM of 20, 25 and 50 days = 100 units
    1 day work of Aman , Bhanu and Cheenu is 5 units, 4 units and 2 units.
    But the nature of work of Cheenu is opposite to that of Aman and Bhanu.
    Let Cheenu work for ‘x’ days and remaining days in which only Aman and Bhanu work is (13 – x) days.
    According to question-
    ⇒ x × (5 + 4 – 2) + (13 – x) × (5 + 4) = 100
    ⇒ x = 8.5 days
    Hence Cheenu left the work after 8.5 days.
