सात अंकी संख्या 52A6B7C ही 33 ने विभाज्य आहे.
वापरलेली संकल्पना:
जर एखाद्या संख्येच्या एकांतरी अंकांच्या बेरजेतील फरक 11 ने विभाज्य असेल, तर ती संख्या पूर्णपणे 11 ने विभाज्य असेल.
जर एखाद्या संख्येच्या अंकांची बेरीज 3 च्या पटीत असेल तर ती संख्या 3 ने पूर्णपणे भाग जाईल.
गणना:
5 + 2 + A + 6 + B + 7 + C = 20 + A + B + C
(A + B + C) चे शक्य असलेले मूल्ये = 1, 4, 7, 10, 13, 16, 19, 22, 25
पुन्हा,
5 + A + B + C - 2 - 6 - 7 = 0 किंवा 11 च्या पटीत
⇒ 5 + A + B + C - 15 = 0 किंवा 11 च्या पटीत
वरील शक्य असलेल्या मूल्यांपैकी, (A + B + C) = 10 साठी आपल्याला 0 मिळते.
म्हणून, A + B + C = 10
आता,
जर A = 5, B = 3, C = 2
2A + 3B + C = 10 + 9 + 2
⇒ 21
जर A = 3, B = 5, C = 2
2A + 3B + C = 6 + 15 + 2
⇒ 23
जर A = 3, B = 2, C = 5
2A + 3B + C = 6 + 6 + 2
⇒ 17
जर A = 2, B = 5, C = 3
2A + 3B + C = 4 + 15 + 3
⇒ 22
तर, 2A + 3B + C चे कमाल मूल्य 23 आहे.
∴ आवश्यक उत्तर 23 आहे.
