[AI-generated answer — Bot GPT 3.5]

Let's assume Morolake's current age is x.

Nine years ago, her age would have been x - 9.
Next year, her age will be x + 1.
According to the given information, (1/4)*(x - 9) = (1/5)*(x + 1).
Multiplying both sides of the equation by 20 (the least common multiple of 4 and 5) to eliminate the fractions, we get 5*(x - 9) = 4*(x + 1).
Expanding the equation, we get 5x - 45 = 4x + 4.
Bringing all the x terms to the left side and the constant terms to the right side, we get 5x - 4x = 4 + 45.
Simplifying the equation, we get x = 49.
Therefore, Morolake is currently 49 years old.
