Answer:
Step-by-step explanation:
Total student - Anu =36-1 =35,
Assume x students are below Anu, Hence 1.5x students will be above Anu.
x + 1.5x =35
2.5x=35
x=14
So Number of students below Anu are x=14
And Number of students above Anu are 1.5x=1.5 * 14 =21
------------------------------------------------------> (Decreasing Order)
21 students---->Anu--------->14 students
Hence Anu rank shall be 21+1 =22nd
