    B's 1 day work x
    A's 1 day work 33.33x/100=(x/3)*(9/5)=3x/5
    Work ratio A:B= 3x/5:x=3x:5x
    So day ratio A:B=5x:3x
    Atq, 1/5x+1/3x=1/15
    X=8
    A needs 40 day, B needs 24 days
    C is 75% as efficient as B, so C needs 32 days
    A,B,C together can do in
    1/40+1/24+1/32
    47/480
    10.21 days(approx.) (ans.)
