Correct answer: (A) 230 tickets
Tickets sold increase by a constant 20 each day (150, 170, 190, 210). So the fifth day's sales = 210 + 20 = 230 tickets.

सही उत्तर: (A) 230 टिकट
प्रतिदिन बिकने वाले टिकटों की संख्या स्थिर रूप से 20 बढ़ती है (150, 170, 190, 210)। इसलिए पाँचवें दिन की बिक्री = 210 + 20 = 230 टिकट।
