Answer:
For a second I thought your birthday was today haha.
Let's begin by creating an equation to reflect the supplied data.
Let x represent my current age.
We are aware of the following:
4/5 x > 3/4 (x + 1)
When both sides are multiplied by 20 (the least common multiple of 5 and 4) the result is:
16x > 15(x + 1)
When the right side is expanded, the following results:
16x > 15x + 15
Subtraction of 15x from both sides results in:
x > 15
My age cannot be less than 16 since it must be an integer number of years.
As a result, the answer is 16.
