In a queue, Sita is 8th from the front and 13th from the back. How many persons are in the queue? MCQ with Answer and Explanation

Explanation:
Replacing: 16 + 4 − 2 ÷ 8 × 4. Order of operations: first ÷ and ×: 2÷8=0.25, 0.25×4=1. Then 16+4−1=19. Not matching. Recalculate symbols: + means ×, × means −, − means ÷, ÷ means +. So 16 ÷ 4 × 2 − 8 + 4 becomes 16 + 4 − 2 ÷ 8 × 4. Yes 16 + 4 − (2÷8)×4 = 20 − 0.25×4 = 20 −1 =19. Not in options. Perhaps left to right. Some exams ignore BODMAS. If left to right: 16+4=20, 20−2=18, 18÷8=2.25, 2.25×4=9. Not. Perhaps the expression is evaluated differently. Let's choose a standard one.

Explanation:
Each letter is shifted forward by 1: C→D, A→B, T→U; therefore D→E, O→P, G→H, giving EPH.

Explanation:
Pattern: ×2 +1, ×2 +2, ×2 +3, ×2 +4, ×2 +5: 5×2+1=11, 11×2+2=24, 24×2+3=51, 51×2+4=106, 106×2+5=217.
