(1)Six year before, the age of mother was equal to the square of her son'sage. Three year hence, her age will be thrice the age of her son then.Find the present ages of the mother and son |
|
Answer» Answer: x = 42 yrs and y = 12 yrs Step-by-step explanation: Given Six years before, the age of mother was equal to the square of her son's age. Let the age of mother be x years and age of the son be y years. six years before means it will be x - 6 and square of the age of her son will be (y - 6)^2 So x - 6 = (y - 6)^2 we have the formula (a -b)^2 = a^2 - 2ab + b^2 x - 6 = y^2 - 12 y + 36 or x = y^2 - 12 y + 42 Given three year hence her age will be thrice the age of her son . So the equation will be x + 3 = 3(y + 3) x = 3y + 6 Substituting in x we have 3y + 6 = y^2 - 12 y + 42 y^2 - 15 y + 36 = 0 y^2 - 12y - 3y + 36 = 0 y(y - 12) - 3(y - 12) = 0 (y - 12)(y - 3) = 0 y = 12, 3 We take y = 12 since 6 yrs ago it will be 3 - 6 = -3 yrs. taking y =12 Given x = 3y + 6 = 3(12) + 6 = 42 Now we get mother's age x = 42 yrs and son's age y = 12 yrs hit like if you find it useful Sir But Age is Not given |

(1) Six year before, the age of mother was equal to the square of her son'soge. Thrce year hence, her age vill he thrice he age of her son them.Find the present ages of the mother and son. |
|
Answer» Explanation - Six years ago let the son age = x Mother = x² Present ages now: Son = x + 6 Mother = x² + 6 3 years later: Son = x + 6 + 3 = x + 9 Mother = x² + 6 + 3 = x² + 9 Solving x - x² + 9 = 3(x + 9) x² + 9 = 3x + 27 x² - 3x - 18 = 0 (x - 6)(x + 3) = 0 x = 6 or x = -3 Take x = 6. As the other value is (- value) Finding their Present age - Son = x + 6 = 6 + 6 = 12 years. Mother = x² + 6 = (6)² + 6 = 42 years. Hence : Son = 12 years Mother = 42 years |
