1) if 40th is the second last then 41th rank is the last. This 41 students in this case.
2) 17th from the middle. This means the middle rank is 5+16=21.
If 21 is the middle, it will mean that on either side of 21 there are 20 students.
so in this case
total students=20+20+1=41
2) 17th from the middle. This means the middle rank is 5+16=21.
If 21 is the middle, it will mean that on either side of 21 there are 20 students.
so in this case
total students=20+20+1=41
