Answer:
Nisha's present age is 5 years
Asha's present age is 27 Years.
Step-by-step explanation:
Let Asha's present age is x years
and Nisha's present age is y years
ATQ
Asha's present age is 2 more than the square of Nisha's present age
So,
We can also write present age of Asha's is
years and her daughter age is x years,so that formation of Quadratic equation in one variable be possible.
Now,when Nisha grows to her mother's present age:
Growing years taken when Nisha: approaches Asha's age: Asha's age-Nisha's age
According to the second condition, Asha's age will be one year less than 10 times of Nisha's present age: Nisha's present age+time span of years calculated in eq2
So,
So,the Nisha's present age is 5 years and her Mother Asha's age is 27 years.
Verification:
Nisha age after 22 years= 27 years(Asha's present age)
After 22 years Asha's age= 22+27=49 Years
I.e. Nisha's present age×10 -1
10×5-1=49
Hope it helps you.
*Note:
We have to discard the second value of x,because it is possible to be the age of daughter,but ATQ then mother's age will be 2.25 years,which is not possible.
