Step-by-step explanation:

96 days

Let time taken by B and C = x days

∴ Time taken by A = 3x days

∴ Part of work done by A, B and C in 1 day

= \frac{1}{x}+\frac{1}{3x} = \frac{3+1}{3x} = \frac{4}{3x}

\therefore \frac{4}{3x} = \frac{1}{24}

=> 3x = 4\times 24

=> x = \frac{4\times 24}{3} = 32\ days

∴ Time taken by A = 32 \times 3 = 96 days.
