Answer:
15 days
Step-by-step explanation:
Lets say A's 1 day Work = 2d
then B's 1 day work = 5d
& C's 1 day work = 3d
Total 1 day work = 2d + 5d + 3d = 10d
Work completed in 27 days
=> total Work = 27 * 10d = 270d
4/9th part of work = (4/9) * 270d = 120d
B & C's 1 day work = 5d + 3d = 8d
B and C together can complete 4/9th part of that work in = 120d/8d = 15
