A వయస్సు, 3 సంవత్సరాల క్రితం B వయస్సు కంటే 2 సంవత్సరాలు ఎక్కువ

లెక్కింపు:

A & B యొక్క ప్రస్తుత వయస్సుల మధ్య నిష్పత్తి 5: 4

A మరియు B వయస్సులను వరుసగా 5x మరియు 4x గా సూచించవచ్చు

3 సంవత్సరాల క్రితం A యొక్క వయస్సు, 4 సంవత్సరాల తరువాత B యొక్క వయస్సు కంటే 2 సంవత్సరాలు ఎక్కువ

(5x - 3) = (4x + 4) + 2

⇒ x = 9

A మరియు B యొక్క మొత్తం వయస్సు = 5x + 4x = 9x 

మొత్తం వయస్సు = 9 × 9 = 81 సంవత్సరాలు
