If 1 is added to each odd digit and 2 is subtracted from each even digit in the number 8317456, what will be the sum of the digits that are second from the left and second from the right?
यदि संख्या 8317456 में प्रत्येक विषम अंक में 1 जोड़ा जाए और प्रत्येक सम अंक में से 2 घटाया जाए, तो बायीं ओर से दूसरे और दायीं ओर से दूसरे अंकों का योगफल कितना होगा?
Detailed Solution & Logic
10
दी गई संख्या:
8317456
Step 1: नियम लागू करें
- विषम अंक (Odd digit) +1
- सम अंक (Even digit) −2
अब हर digit पर लागू करते हैं:
- 8 (even) → 8 − 2 = 6
- 3 (odd) → 3 + 1 = 4
- 1 (odd) → 1 + 1 = 2
- 7 (odd) → 7 + 1 = 8
- 4 (even) → 4 − 2 = 2
- 5 (odd) → 5 + 1 = 6
- 6 (even) → 6 − 2 = 4
👉 नई संख्या = 6428264
Step 2: Position देखें
- बायीं ओर से दूसरा अंक = 4
- दायीं ओर से दूसरा अंक = 6
➕ Step 3: योग
4 + 6 = 10
Final Answer:
👉 10 (सही विकल्प: 3)
