The total number of students cannot be determined because the ranks of Sairam from top and bottom is given for different subjects. So, the given information is not sufficient. Hence, option (d) is correct.
Given number = 53146872
After interchanging the digits,
New number = 68725314
Hence, fifth digit from the right end = 2
Total number of students = Total of both side rank - 1 = 21 + 30 - 1 = 50
Dhanbad > Palamu > Para Banki > Fatehpur > Akbarpur. Hence, Dhanbad district is biggest amongst them
5 3 1 6 9 7

Perfect square = 576
Square root = ?576 = 24
Hence, second digit = 4
Arranging all birds in descending order according to distance,
Little pigeon > Crow > Pigeon > Big crow > Eagle.
Hence, Eagle is the last.
Dilip is 10th from the left and the same position is occupied by Jagdish after interchanging takes place and he becomes 23rd from the right.
Therefore, total number of student in the row = (10 + 23) - 1 = 32
Position of Rekha is 20th from the right which is occupied by Jaya after interchanging takes place and Jaya becomes 22nd from the left. Therefore, total number of students in the row.
(20 + 22) - 1 = 41
From among those who passed Neeta is 22nd from the top and Kalyan is 22 +5 = 27th from the top and 34th from the bottom. Therefore, total number of students who passed the examination = 27 + 34 - 1 = 60.
Therefore, total number of students in the class = (60/4) X 5 = 75

but Seema was present on 23rd. Also, it was holiday on 24th and 26th October was Sunday. Hence, possible date may be either 22nd or 25th October
According to question,
R is heavier than S but lighter than T.
R > S But T > R
Then T > R > S
P is lighter than S.
S > P
Then
T > R > S, S > P ? T > R > S > P
But information about Q is not given, Hence, either T or Q is the heaviest.
