Download Solution PDFदिया गया है:
A और B की वर्तमान आयु का अनुपात 2 ∶ 3 है।
5 वर्ष बाद उनकी आयु का अनुपात 3 ∶ 4 होगा।
गणना:
मान लीजिए A और B की वर्तमान आयु 2x और 3x है।
प्रश्न के अनुसार,
\(\frac{2x +5}{3x + 5} = \frac{3}{4}\)
⇒ 8x + 20 = 9x + 15
⇒ 20 - 15 = 9x - 8x
⇒ x = 5
इसलिए, B की वर्तमान आयु = 3 × 5
⇒ 15 वर्ष
∴ B की वर्तमान आयु 15 वर्ष है।
