Answer:
- Vicky one day work 1/15
- Arun one day work 1/10
they work together
work done by Vicky and Arun in one day
1/15 + 1/10 = 2 + 3/30
5/ 30 = 1/6 work
If 1/6 work done by Vicky and Arun in one day
if 1 work done by Vicky and Arun = 1/ 1/6
1*6 = 6 day
work completed in 6days when they work together
