Answer 2

Given,

Ram's rank from the top is 12.

Ramesh's rank from the bottom is 27.

After interchanging Ram's rank becomes 18from the top.

To Find,

The number of students in the class.

Solution,

Given that,

$12^{th}$is the rank of Ram from the top.

$27^{th}$ is the rank of Ramesh from the bottom.

That means,

There are 11 students are above Ram.

And 26 students are below Ramesh.

After they interchanged their positions,

Ram's rank became at $18^{th}$ .

Then,

there will be 17 students above.

As Ram is now in Ramesh's position there are 26 students below Ram.

Therefore,

Total students = 17+26+1

TS = 44.

Option(D) 44 is the number of students in the class.
