Sonam is 8 ranks ahead of Soniya who ranks twenty-sixth in a class of 45. What is Sonam's rank from the last?

Solution

✅ Correct Option: 4

Soniya ranks 26th in the class.

Sonam is 8 ranks ahead of Soniya, meaning Sonam has a better rank (lower rank number).

Sonam's rank from the top:

Sonam’s rank=26−8=18\text{Sonam's rank} = 26 - 8 = 18


The class has 45 students in total.

For a student at rank rr from the top in a class of nn students, the rank from the last is given by:

Rank from last=n−r+1\text{Rank from last} = n - r + 1


Sonam's rank from the last:

Rank from last=45−18+1\text{Rank from last} = 45 - 18 + 1

Rank from last=28\text{Rank from last} = 28

Therefore, Sonam's rank from the last is 28.
