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
Answer:
nisha age: 5 years
Asha age: 27 years
