x3331
ఉపయోగించిన భావన:
సంఖ్య యొక్క ప్రత్యామ్నాయ అంకెల మొత్తం యొక్క వ్యత్యాసం 11 ద్వారా భాగించబడినట్లయితే, ఆ సంఖ్య పూర్తిగా 11 ద్వారా భాగించబడుతుంది.
లెక్కింపు:
x3331 ప్రత్యామ్నాయ ప్రదేశాలలో అంకెల మొత్తానికి మధ్య వ్యత్యాసం
⇒ (x + 3 + 1) - (3 + 3)
⇒ x + 4 - 6
⇒ x - 2
ఇప్పుడు, x 2 మాత్రమే అవుతుంది, ఇది (x - 2) = 0ని 11తో భాగించవచ్చు. (∵ x 1 నుండి 9 వరకు ఏదైనా పూర్ణాంకం కావచ్చు)
కాబట్టి, x = 2
∴ x ముఖ విలువ 2.
