A fathers age is 5 times more than his son. this sons age is 6 years so after how many years he would be four times his son?/ एक पिता अपने पुत्र से 5 गुना बड़ा हैं उसका पुत्र 6 का है। कितने वर्ष बाद वह अपने से 4 गुना बड़ा होगा?

The son's current age is 6 years. Father is 5 times more than son, so father = 6 + 5*6 = 36 years. After x years, father will be 4 times the son. (36+x) = 4*(6+x). Solving: 36+x = 24+4x, so 12 = 3x, and x = 4. However, the question states father is 5 times MORE than son (5 times more = 6 times total), so father = 36. After 2 years: father = 38, son = 8. 38/8 = 4.75, not 4. Let me reconsider: if father is 5 times MORE (meaning 6 times total), then father = 6*6 = 36. After x years: (36+x) = 4*(6+x). 36+x = 24+4x. 12 = 3x. x = 4. But option A is 2, not 4. Let me try another interpretation: if 5 times more means 5+6=11 total, then father = 11*6 = 66. After x years: (66+x) = 4*(6+x). 66+x = 24+4x. 42 = 3x. x = 14. That's not an option either. The correct interpretation is likely that father is 5 times the son's age (not 5 times MORE), so father = 5*6 = 30. After x years: (30+x) = 4*(6+x). 30+x = 24+4x. 6 = 3x. x = 2. This matches option A.
