Correct Answer: 24 days


Solution : (9 boys + 12 men) complete the work in 24 days.
The ratio of time taken by a boy and time taken by a man = 3 : 1
i.e., 3 boys are equivalent to 1 man.
$\therefore$ 9 boys are equivalent to 3 men.
So, (3 men + 12 men) are equivalent to 15 men
So, 15 men complete the work in 24 days.
Hence, the correct answer is 24 days.
