Question 143

# What is Sunita’s rank from the top in the class of 40 students ?I. Rani is 4 ranks below Sunita and is thirty first from the bottom.II. Amit is two ranks above Sunita and is thirty seventh from the bottom.

Solution

Total number of students = 40

I : Rank of Rani from bottom = 31

=> Rank of Rani from top = 40 - 31 + 1 = 10

=> Rank of Sunita from top = 10 - 4 = 6th

Thus, I alone is sufficient.

II : Rank of Amit from bottom = 37

=> Rank of Amit from top = 40 - 37 + 1 = 4th

=> Rank of Sunita from top = 4 + 2 = 6th

Thus, II alone is sufficient.

$$\therefore$$ Either statement alone is sufficient.
