Question

Ten years ago,prisha's age was the square of her sisters age.11 years hence she will be 6 years older to her sister.find their present age

Answer 1

Very badly framed question. The square of which number is six greater than itself? \(3\). Now, they must be \(13\) and \(19\).

Answer 2

"11 years hence she will be 6 years older to her sister.find their present age"

this means that they currently differ by six years too. they will ALWAYS differ by six years, not only eleven years later.

Answer 3

older than her sister **

Answer 4

If you want a quadratic equation, just try this:
Let the present ages of Prisha and her sister be \(x\) and \(x-6\).\[(x-6-10)^2 = x-10\]

Answer 5

Ten years ago,Prisha's age was the square of her sisters age.
Eleven years hence,she will be 6 years older than her sister.
