Failed Students
= [ Total students ] ? [ (Anmol's position from upwards) + (Anmol's position from downwards) ? 1 ]
= 45 ? [(11 + 15) ? 1] = 20
The possible date of birth of Ana according to Adi are 21st and 22nd September. But according to his father Ana's date of birth should be 22nd and 23rd September. Now after both conclusion there is 22nd September common date, so answer is that (b).
After exchanging positions, Bhusan becomes fifteenth instead of seventh from the left, it means there are 7 students between them. So Motilal's position from the right will become twelfth. [i.e., (15 ? 7) + 4 = 12]
Number of persons between Vijay and Jack = 48 ? (14 + 17) = 17
Now, Mary lies in middle of these 17 persons i.e, at the eighth position.
So, number of persons between Vijay and Mary = 7.
Total students = [ First position of Ganesh + Second position of Rajan ] ?1
Total students = [12 + 20] ? 1 = 31
According to given question,
If the positions of the first and the sixth digits of the group of digits 3 5 9 7 2 8 0 1 6 4 are interchanged.
New number after interchange = 8 5 9 7 2 3 0 1 6 4
Then the positions of the second and the seventh digits are interchanged.
New number after interchange = 8 0 9 7 2 3 5 1 6 4
After interchanging the number becomes as follows: 8 0 9 7 2 3 5 1 6 4
fourth digit from the right end after the rearrangement : 5
If the first working day happened to be Tuesday then 8th, 15th, 22nd and 29th of the month will be Tuesday. Hence, the last day of the month will be Wednesday (since, number of days in the month is 30). Thus, the next casual leave will be on Thursday.
Anil reached the place on Friday and he was three days earlier than the scheduled day.
Therefore, the scheduled day = Friday + 3 days = Monday
If he had reached on Sunday then he would have earlier than one day.
i.e. Monday - one day = Sunday
Here , Day before yesterday was Sunday.
Therefore, today is Tuesday.
Day after tomorrow will be Thursday.
? Thursday + 3 days = Sunday
Hence , required day will be Sunday .
Given that :- Friday ? 2 days earlier
Therefore, scheduled day = Friday + 2 days = Sunday,
Sunday + 3 days = Wednesday
Therefore, I would have been late by 4 days including Sunday.
Given :- 15th June falls 3 days after tomorrow ,
Tomorrow ? Friday
Friday + 3 days = Monday
Monday = 15th
Other Monday ? 22, 29
Therefore, 30th June = Tuesday
Hence , required day will be Tuesday .
