Mathematics

Asha's present age is 27 years and Nisha's present age is 5 years.

Step-by-step explanation:

Let the present age of Nisha be years.

As per question, Asha's present age is 2 more than the square of Nisha's age.

$\therefore$ Asha's present age = x^2+2

Now, Nisha will reach her mother's age after x^2+2-x years.

Therefore, age of Asha after x^2+2-x years will be = x^2+2+x^2+2-x=2x^2-x+4

Now, as per question,

$2x^2-x+4=10x-1\\2x^2-x-10x+4+1=0\\2x^2-11x+5=0\\2x^2-x-10x+5=0\\x(2x-1)-5(2x-1)=0\\(2x-1)(x-5)=0\\x=\frac{1}{2}\ or\ x=5$

As age can't be in fraction, we consider the present age of Nisha as 5 years. So, Asha's present age is x^2+2=5^2+2=25+2=27 years.

Therefore, Asha's present age is 27 years and Nisha's present age is 5 years.
