Final answer:
Pankaj's rank in the overall class ranking is determined to be 4th based on Priya's rank among girls and her position relative to Pankaj.
Step-by-step explanation:
To find the rank of Pankaj in the class, we need to consider Priya's rank among the girls and Pankaj's rank among the boys, as well as how Priya's overall rank relates to Pankaj's
The total number of students in the class is 40. Priya ranks 6th among the girls in the class, and Pankaj ranks 5th among the boys. Since Priya is 2 ranks below Pankaj, we can calculate Pankaj's rank by subtracting 2 from Priya's rank among the girls. Therefore, Pankaj's rank in the class is 4th.
Priya ranks 6th among the girls and she is 2 ranks below Pankaj. This means Pankaj is 4th when counting from the top in the overall class ranking because Priya is 6th and Pankaj is two places ahead of her.
To confirm, let's assume the number of girls ahead of Priya (5) plus the number of boys ahead of Pankaj (4) should be 1 less than Pankaj's overall rank, because one of the top spots is occupied by Pankaj himself. So, 5 (girls) + 4 (Pankaj) = 9, confirming that Pankaj is 4th in the overall class ranking.
Therefore, Pankaj's rank in the class is 4th.
