Detailed Solution
Download Solution PDFఉపయోగించిన భావన:
11 కోసం భాగాహార నియమాలు:
సంఖ్య యొక్క ప్రత్యామ్నాయ అంకెల మొత్తం యొక్క భేదం 11 ద్వారా భాగించబడినట్లయితే, ఆ సంఖ్య పూర్తిగా 11చే భాగించబడుతుంది.
గణన:
13y7 11చే భాగించబడుతుంది,
కాబట్టి, 13y7 = 1 + y = 3 + 7
⇒ y = 10 - 1 = 9
సంఖ్య 1397.
ప్రశ్న ప్రకారం,
4x3 + 984 = 1397
⇒ 4x3 = 1397 - 984
⇒ 4x3 = 413
⇒ x = 1
ఇప్పుడు, (x + y) = 1 + 9 = 10
∴ (x + y) = 10
