    Explanation:
    Time taken by J to do the work = 20/5 × 6 = 24 days
    Let total work = LCM (15, 12, 24) = 120 unit
    One day work of B = 120/15 = 8 unit
    One day work of C = 120/12 = 10 unit
    One day work of J = 120/24 = 5 unit
    Work done by C and J in 3(2/5) days = (10 + 5) × 17/5 =51 unit
    Remaining work = 120 – 51 = 69 unit
    No. of day for which B, C and J worked together = 69/ (8+ 10 + 5) = 69/23 = 3 day
    ∴ B left the work after 3 days
