raj and his sister zia are both at secondary school. Raj is three years older than zia. the sum of the squares of their ages is

steposvetlana [31]

Let's assume

Raj's age is x years

Zia's age is y years

we are given

Raj is three years older than zia

so, we get

$x=y+3$

now, we can solve for y

$y=x-3$

the sum of the squares of their ages is 369

so, we get

$x^2+y^2=369$

now, we can plug back y

$x^2+(x-3)^2=369$

now, we can solve for x

$2x^2-6x+9=369$

$2x^2-6x-360=0$

$x^2-3x-180=0$

$(x+12)(x-15)=0$

$x=-12 , x=15$

Since, age can not be negative

so, we will only consider positive

$x=15$

now, we can find y-value

$y=15-3$

$y=12$

So,

Raj's age is 15 years

Zia's age is 12 years...........Answer
