    Explanation

    Solution: C's 1 days work  13−(16+18)\frac{1}{3} - (\frac{1}{6} + \frac{1}{8})      => 13−724\frac{1}{3} - \frac{7}{{24}}    => 124\frac{1}{{24}} part C's 3 day's work = 324=18\frac{3}{{24}} = \frac{1}{8} part C's share (for 3 days) = Tk 3200×183200 \times \frac{1}{8} = 400 Tk.
