ong>Answer:

so neha's present AGE is 5 years

Step-by-step explanation:

Let Nisha's age is x years

Aisha's age = (x² + 2) years

Now, A/C to question , when Nisha grows to her mother present age .means Nisha's grows = Aisha's present age - Nisha's present age = x² + 2 - x

Then, this TIME Aisha's age = Aisha's present age + growing time = x² + 2 + x² + 2 - x = 2x² - x + 4

Now, question said , Aisha's age = 10× times of Nisha's age -1

2x² - x + 4 = 10X -1

2x² - 11x + 5 = 0

2x² -10x - x + 5 = 0

x = 5 and 1/2 x ≠ 1/2 because age doesn't in moths

Hence , Nisha's present age = 5 years

Aisha's present age = (5)² + 2 = 27 years
