In a class test Suruchi is ranked 21st from the top as well as from the last.
total students in the class = 21×2-1 = 41
rank of Shanti from top is = rank of suruchi - 10 = 21-10= 11
Rank of Tanu from top = rank of Shanti- 5= 11-5 = 6
So , Rank of Tanu from last is =( 41+1)-6 = 36th [ +1 is added because 41th rank is itself rank 1 from last , 40= 2nd , as an example 40th tank is rank 2 from last as their is 41 students , simple substraction is not applicable +1 should be added for calculation purposes]
