Answer:

Correct Answer:

B) 15 days

Description for Correct answer:

A works alone for 2 days and finishes 220 or 110th of the work.

On the 3rd day A, B and C finish 120+130+160=110th of the work.

or in 3 days, 110+110=15th of the work is completed.

Therefore, the job will be completed in 5×3 = 15 days.
