Question

Oha ranks 5th in the class. How many students are there in the class? Statements: i) one of her friends got the 40th rank which is the second last rank in the class. Ii) her rank from the middle is 17.

Answer 1

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
