23, At present Asha's age (in years) is 2 more than the square of her daughter Nisha's age. WhenNisha grows to her mother's present age, Asha's age would be one year less than 10 timesthe present age of Nisha. Find the present ages of both Asha and Nisha. |

Answer» Let the age of Nisha be x. Then Age of Asha = y = 2+ x^2.Difference between age of Asha and Nisha = x^2 - x + 2 = y -x .When Nisha grows to Asha's present age, Nisha's age = x^2 + 2. 2*x^2 -x + 4 = 10x - 1=> 2x^2 - 11x + 5 = 0=> 2x^2 - 10x - x + 5 = 0=> 2x( x - 5) - 1(x -5) = 0=> (x - 5)(2x - 1) = 0=> x = 5. Nisha's age = 5 years. Asha's age = 27 years. PLEASE HIT THE LIKE BUTTON |
