Explanation:

Bhaskar can complete the work in (10 x 8 ) = 80 hours
Vishal can complete the work in (8 x 6 ) = 48 hours.
Bhaskar's 1 hour's work = 1/80 and Vishal's 1 hour's work = 1/48hours.
(A +B)'s 1 hour's work = (1/80+1/48)= 1/30
Both will finish work in 30 hours
Number of days of 6 hour each = 30/6 = 5 days
