संख्या = 3823P8
11 से विभाज्य
प्रयुक्त सूत्र:
11 का नियम: (विषम स्थानों पर अंकों का योग) - (सम स्थानों पर अंकों का योग) ≡ 0 (mod 11)
गणना:
अंक: 3, 8, 2, 3, P, 8
विषम स्थान (प्रथम, तृतीय, पंचम): 3, 2, P → योग = 3 + 2 + P = 5 + P
सम स्थान (द्वितीय, चतुर्थ, षष्ठ): 8, 3, 8 → योग = 8 + 3 + 8 = 19
⇒ (5 + P) - 19 ≡ 0 (mod 11)
⇒ P - 14 ≡ 0 (mod 11)
⇒ P ≡ 14 (mod 11)
⇒ P = 14 - 11 = 3
∴ P का मान = 3
