Answer

A's 1 day work = 16\dfrac{1}{6}

B's 1 day work = 112\dfrac{1}{12}

C's 1 day work = 124\dfrac{1}{24}

(A + B + C)'s 1 day work = 16+112+124\dfrac{1}{6} + \dfrac{1}{12} + \dfrac{1}{24}

= 4+2+124\dfrac{4 + 2 + 1}{24}

= 724\dfrac{7}{24}

A + B + C can do the work in 247=337\dfrac{24}{7} = 3\dfrac{3}{7} days

Hence, A + B + C can do the work in 3373\dfrac{3}{7} days.
