एका दोन अंकी संख्येतील अंकाची बेरीज 8 आहे, दशम स्थानातील अंक एकम् स्थानाच्या अंकांच्या तिप्पट असेल तर ती संख्या कोणती ?

The correct answer is Option A (62).

Key Points:
• This is a classic word problem involving two-digit numbers. The fastest way to solve this is by testing the given options against the conditions.
• Condition 1: The sum of the digits must be 8.
• Opt 1: 6 + 2 = 8 (Satisfies)
• Opt 2: 5 + 3 = 8 (Satisfies)
• Opt 3: 7 + 1 = 8 (Satisfies)
• Opt 4: 9 + 3 = 12 (Eliminated)
• Condition 2: The digit in the tens place is three times the digit in the units place (Tens digit = 3 × Units digit).
• Opt 1 (62): Tens digit is 6, Units digit is 2. Is 6 = 3 × 2? Yes! (Satisfies)
• Opt 2 (53): Tens is 5, Units is 3. Is 5 = 3 × 3? No.
• Opt 3 (71): Tens is 7, Units is 1. Is 7 = 3 × 1? No.
• Therefore, 62 is the only number satisfying both conditions. Option 1 is correct.
• Key Takeaway: Check conditions via options: In 62, sum is 8 (6+2) and tens digit (6) is exactly three times the unit digit (2).
