@anshulgurawalia dont think like this if you are trying for 4 students then think like this that we have total of 15 coupons now : and if one students is giving the criteria of fail and he will give 3 cuupons and then total we have 18 but for four students we need 20 coupons (5*4) and we dont have this much coupons thats why we are not able to give 4th student the 100%scholarhship.
