Correct answer: (A) 48
Let Rahul's age = x, Mohit's = 3x. After 12 years: 3x+12 = 2(x+12), which gives x = 12. So Mohit = 36, Rahul = 12, and the sum of their present ages = 48.

सही उत्तर: (A) 48
मान लीजिए राहुल की आयु x और मोहित की आयु 3x है। 12 वर्ष बाद: 3x+12 = 2(x+12), जिससे x = 12 मिलता है। अतः मोहित = 36, राहुल = 12, और वर्तमान आयु का योग = 48।
