Correct option is D
Given:
Anjali can complete a job in 10 days.
Banu can do it in 5 days.
Formula Used:
Work = Time Efficiency

Total work = LCM of (10, 5) = 10 unit
Efficiency of Anjali = 10/10 = 1 unit/day
Efficiency of Banu = 10/5 = 2 unit/day
The work will complete when they done work together
