Detailed Solution
Download Solution PDFदिलेले आहे:
12 वर्षांपूर्वी, सुधीर आणि आशिष = 1 : 2
सुधीर आणि आशिषचे सध्याचे वय = 5 :7
वापरलेली संकल्पना:
आपण गुणोत्तर संकल्पना वापरणार आहोत.
गणना:
सुधीर आणि आशिष यांचे 12 वर्षांपूर्वीचे वय = अनुक्रमे 1x आणि 2x,
प्रश्नानुसार,
(1x + 12) / (2x + 12) = 5/7
⇒ 7x + 84 = 10x + 60
⇒ 3x = 24
⇒ x = 8
∴ सुधीरचे सध्याचे वय = 8 + 12 = 20 वर्षे
आजपासून पाच वर्षांनी सुधीरचे वय = 20 + 5 = 25
आजपासून पाच वर्षांनी सुधीरचे वय 25 वर्षे आहे.
Shortcut Trick
आपण प्रथम वयातील अंतर समतुल्य करू, कारण ते स्थिर राहते.
आजपासून पाच वर्षांनी सुधीरचे वय = 20 + 5 = 25
