Detailed Solution
Download Solution PDFपीटर आणि प्रीतीचे वय अनुक्रमे A आणि B मानू.
पीटर आणि प्रीतीच्या वयात 5 वर्षांचा फरक आहे,
⇒ A – B = 5
35 वर्षांपूर्वी, पीटरच्या वयाची 4 पट प्रीतीच्या वयाच्या 5 पटीइतकी होती,
⇒ 4(A – 35) = 5(B – 35)
⇒ 4A – 140 = 5B – 175
⇒ 5B – 4A = 35
सोडवल्यानंतर,
⇒ 5B – 4(5 + B) = 35
⇒ 5B – 20 – 4B = 35
⇒ B = 55
⇒ A = 60
∴ त्यांच्या सध्याच्या वयाची बेरीज = 60 + 55 = 115 वर्षेLast updated on Jun 2, 2025
