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
