10 sleepers for easy of calculation check for lower quota in which per coach SL we get 7LB seats for lower quota so it has 70 seats for lower quota which means 10 Sleeper.
And 4LB for 3A and 2A which is having 20LB in 3A and 8LB in 2A that means 5-3A and 2-2A and 1 complete AC first
Note- It varies for train to train based on distance and quota alignment and will not work for the trains greater 1100KM.
