• There are three horizontal rows i.e., Row 1, Row 2, and Row 3. Row 1 is north of Row 2, which is north of Row 3. All people sitting in the row are facing North. The length of each row is 30 m. The distance between each of the adjacent persons in row 1 is 6m, in row 2 is 5m and in row 3 is 10m. No seat is vacant.
• In row 2, The distance between F and B is the same as the distance between B and C.
• In row 1, the distance between R and N is 24m.
• The distance between E and C is 10m in row 2, where C sits to the right of E and F.
• So, there are two cases possible i.e., Case 1 and Case 2.
• The distance between A and D is half the distance between T and V, where A and D sit in Row 2 and T and V in row 3.
• F does not sit adjacent to D.
• V does not sit adjacent to U.
• T sits to the left of V.
• In row 3, the distance between U and T is 20m, where U sits to the left of T.
• So, Case 1 will further have two cases i.e., Case 1(a) and Case 1(b).
• Q sits adjacent to M and O in row 1, where R do not sit adjacent to O.
• So, Case 2 will be invalid.
• S and G sits in Row 3 and Row 2 respectively.
• In row 1, N sits immediate left of P.
• So, Case 1(a) will be invalid.
Finally, we get,
The distance between Q and P is 18m.
