A, B से 8 वर्ष छोटा है।
4 वर्ष पहले, A और B की आयु का अनुपात = 1 : 2
गणना:
माना, A की वर्तमान आयु = x वर्ष
इसलिए, B की वर्तमान आयु = (x + 8) वर्ष
तब, (x - 4)/[(x + 8) - 4] = 1/2
⇒ (x - 4)/(x + 4) = 1/2
⇒ 2x - 8 = x + 4
⇒ 2x - x = 8 + 4
⇒ x = 12
इसलिए, B की वर्तमान आयु = 12 + 8 = 20 वर्ष
∴ B की वर्तमान आयु (वर्षों में) 20 वर्ष है।
