Concept:The relation is: (First Number × Second Number) − 5 = Third Number.Explanation:For (18, 5, 85): $18 \times 5 = 90$, then $90 - 5 = 85$.For (11, 7, 72): $11 \times 7 = 77$, then $77 - 5 = 72$.Now check each option using the same relation.Option A: (15, 6, 85) → $15 \times 6 = 90$, then $90 - 5 = 85$. This matches.Option B: (10, 8, 85) → $10 \times 8 = 80$, then $80 - 5 = 75 \neq 85$.Option C: (8, 4, 32) → $8 \times 4 = 32$, then $32 - 5 = 27 \neq 32$.Option D: (9, 7, 68) → $9 \times 7 = 63$, then $63 - 5 = 58 \neq 68$.Answer:Option A, (15, 6, 85), follows the same relation.
