Correct answer: (B) 250
Let a = adult tickets, c = child tickets. a + c = 500 and 20a + 12c = 8000. Substituting c = 500 - a: 20a + 12(500-a) = 8000 → 8a + 6000 = 8000 → 8a = 2000 → a = 250 adult tickets.

सही उत्तर: (B) 250
मान लें a = वयस्क टिकट, c = बच्चों के टिकट। a + c = 500 और 20a + 12c = 8000। c = 500 - a रखने पर: 20a + 12(500-a) = 8000 → 8a + 6000 = 8000 → 8a = 2000 → a = 250 वयस्क टिकट।
