1) M sits sixth to the one who lives in Delhi, who sits third to the right of N.
2) Seven people sit between K and N, who sits eleventh from one of the ends of the row.
Case 1)
Case 2)
Case 3)
3) The one who lives in Mumbai sits four places away from N.
4) The one who lives in Mumbai and the one who lives Delhi do not sit near each other.
5) L sits second to the right of J, who sits fourth to the left of the one who lives in Mumbai.
Case 1)
Case 2)
Case 3)
6) The one who lives in Jaipur sits immediately between K and T, who sits at one of the ends of the row.
7) Two people sit between the one who lives in Kolkata and the one who lives in Jaipur.
As there is no possible position for T in case 1, therefore is eliminated.
Case 2)
Case 3)
7) Exactly two people sit between P and R, who is six places away from the one who live in Jaipur.
8) A sit to the immediate left of P who sits second to the left of the one who lives in Chandigarh.
Case 2)
Case 3)
9) D sit somewhere to the left of A.
10 The number of people sitting to the left of D is two more than the number of people sitting between K and P.
As there is no possible position for D in case 2, therefore is eliminated.
Case 3)
Thus, according to the final arrangement, 19 people sit in the row.
Hence, "Option 5" is the correct answer.
