पिता की वर्तमान आयु का उसके पुत्र की आयु से अनुपात = F : S = 7 : 2
गणना:
माना, पिता की वर्तमान आयु (F) = 7x
पुत्र की वर्तमान आयु (S) = 2x
प्रश्न के अनुसार:
⇒ (7x + 10)/(2x + 10) = 9/4
⇒ 28x + 40 = 18x + 90
⇒ 28x - 18x = 90 - 40
⇒ 10x = 50
⇒ x = 5
इसलिए, पिता की वर्तमान आयु (F) = 7x = 7 × 5 = 35 वर्ष
∴ सही उत्तर 35 वर्ष है।
