Question

A mother's age is a square of her daughter's age. After 5 years, mother will be three times as old as her daughter. What is the present age of the mother? Please do it in simple method. And keep in mind that it should be very easy

Answer 1

hi bro!
# your solution here:

Let the daughter age be X
then her mother age be x^2

now

after 5 years

x^2 +5 = X+5

then five years later mother age Will be 3 times as old her daughter

so

x^2 +5 = 3( X+5)

x^2 +5 = 3x +15

x^2 -3x +5 -15 =0

x^2 -3x -10=0

now factorise


x^2 -5x +2x -10 =0

X(X -5) +2 (x-5) =0

(x-5) (X+2) =0

X = 5,-2

X can not be negative


so
X = 5

daughter age be 5 years
&
her mother age be =5^2 = 25 years
