According to the question,
A's 1 day work = 1/24.
B's 1 day work = 1/9.
C's 1 day work= 1/12.

(B+C)'s 1 day work = 1/9 + 1/12 = 21/108 = 7/36.
(B+C)'s 3 day work = (7/36) x 3 = 7/12.
Remained work = 1- 7/12 = 5/12.

Since, A do 1/24th of the work in 1 day.
then, he will do 5/12th part of work in 24 * (5 / 12) = 10 days.
