Answer 1

Answer:

Rank of Anu = 22

Step-by-step explanation:

In the question,

Total number of students in the test = 36

Let us take the number of contestants above Anu = y

And,

Number of contestants below Anu = (35 - y)

So,

According to the question,

$y=\frac{3}{2}(35-y)\\2y=105-3y\\5y=105\\y=21$

Therefore,

The number of students above Anu = 21

And,

Number of students below Anu = 14

So,

On putting the rank in the decreasing order,

The rank of Anu is 22nd.
