In 3 years, the sum of their present ages will be added by 3 (from Allen) + 3 (from her mother) = <<3+3=6>>6.

So, the sum of their present ages is 41 - 6 = <<41-6=35>>35.

Let x be the present age of Allen's mother and x - 25 be the present age of Allen.

So the equation using the sum of their present ages is x + x - 25 = 35.

By combining like terms, the equation becomes 2x = 60.

Hence, Allen's mother is x = 60/2 = <<60/2=30>>30 years old now.
