Jenny is four times as old as her niece tina in 12 years jenny will be only twice as old as tina

Let’s say that the present age of Marina’s daughter is ‘x’ years. Then 4 years ago, her age was (x - 4) years. Therefore, Marina’s age 4 years ago was: (x - 4) + 3(x - 4) = 4(x - 4) years. 6 years from now, the daughter’s age will be (x + 6) years, and Marina’s age will be: 2(x + 6) years.Now, 6 years from now will be (6+4), i.e., 10 years away from 4 years ago. Thus, Marina’s age 6 years from now can also be written as 4(x - 4) + 10 = (4x - 6) years. Therefore, 2(x + 6) = 4x - 6. Or, 2x + 12 = 4x - 6.

Or, 2x = 18.

Thus, the daughter’s age (x) = 9 years, and Marina’s present age = 4(x - 4) + 4 = 24 years.
