Detailed Solution
Download Solution PDFमाना पीटर और प्रीति की आयु क्रमशः A और B है।
पीटर और प्रीति की आयु के बीच का अंतर 5 वर्ष है,
⇒ A – B = 5
35 वर्ष पहले, पीटर की आयु का 4 गुना प्रीति की आयु के 5 गुना के बराबर था।
⇒ 4(A – 35) = 5(B – 35)
⇒ 4A – 140 = 5B – 175
⇒ 5B – 4A = 35
हल करने पर,
⇒ 5B – 4(5 + B) = 35
⇒ 5B – 20 – 4B = 35
⇒ B = 55
⇒ A = 60
∴ उनकी वर्तमान आयु का योग = 60 + 55 = 115 वर्षLast updated on Jul 17, 2025
