As many person born before Ankush as many person after Nidhi.Â
Why this answer is correct
-
Atmost two person born before Kritika.                                Â
-
Nidhi born in a leap year.            Â
-
As many person born before Kritika as after Arpita.
| Year | Age | Case – 1 | Case – 2 | Case – 3 |
|---|---|---|---|---|
| Person | Person | Person | ||
| 1983 | 42 | Kritika | ||
| 1987 | 38 | Kritika | ||
| 1995 | 30 | Kritika | ||
| 1998 | 27 | |||
| 2004 | 21 | Nidhi | Nidhi | Nidhi |
| 2007 | 18 | Arpita | ||
| 2011 | 14 | Arpita | ||
| 2014 | 11 | Arpita |
Â
 5) Aarav’s age is a prime number. So, case 3 is eliminated because we cannot place Aarav at any place.
-
Difference between age of Aryan and Arpita is a perfect square of least prime number where Aryan is older than Arpita.
-
As many person born between Ram and Ankush as many person between Ankush and Arpita.
| Year | Age | Case – 1 | Case – 2 |
|---|---|---|---|
| Person | Person | ||
| 1983 | 42 | Ram | |
| 1987 | 38 | Ram | Kritika |
| 1995 | 30 | Kritika | |
| 1998 | 27 | Ankush | Ankush |
| 2004 | 21 | Nidhi | Nidhi |
| 2007 | 18 | Arpita | Aryan |
| 2011 | 14 | Aryan | Arpita |
| 2014 | 11 |
Â
Since, In case – 2 Aryan is older than Arpita is follow the given condition but incase – 1, it is not follwoed so we eliminate case – 1 . Therefore, the final arrangement is as follows
| Year | Age | Person |
|---|---|---|
| 1983 | 42 | Ram |
| 1987 | 38 | Kritika |
| 1995 | 30 | Alisha |
| 1998 | 27 | Ankush |
| 2004 | 21 | Nidhi |
| 2007 | 18 | Aryan |
| 2011 | 14 | Arpita |
| 2014 | 11 | Aarav |
Â
Hence, people born before Ankush and after Nidhi is same.
