UPSSSC PET 2026 (25 Oct Shift 1)
Six persons (A, B, C, D, E and F) are sitting in a row, all facing North. C sits immediately to the left of B and is the third person to the right of A. D sits at the extreme right end. If E sits immediately to the right of F, who sits at the extreme left end ?
Answer (Detailed Solution Below)View answer ▾Hide ▴
Answer: Option C — A
Detailed Solution
Number seats 1–6 from the left; D is at seat 6.
C is third to the right of A and B is just right of C, so A, C, B take seats a, a+3, a+4. With seat 6 taken, a = 1: A = 1, C = 4, B = 5.
F and E take seats 2 and 3 (E right of F). Order: A F E C B D, so A sits at the extreme left.
