Let the daughter's present age be x years. Then the man's present age is 6x years. After 4 years, the man's age will be 6x + 4, and the daughter's age will be x + 4. Given: 6x + 4 = 4(x + 4). 6x + 4 = 4x + 16. 2x = 12 → x = 6 years. So, the man's current age is 6 * 6 = 36 years. Let y years later, the man’s age will be 3 times the daughter’s age. 36 + y = 3(6 + y). 36 + y = 18 + 3y. 2y = 18 → y = 9 years.
