Question : For real $a, b, c$ if $a^2+b^2+c^2=ab+bc+ca$, then value of $\frac{a+c}{b}$ is:
Option 1: 1
Option 2: 2
Option 3: 3
Option 4: 0
Correct Answer: 2
Solution : Given: $a^{2} + b^{2} + c^{2} = (ab+bc+ca)$ ⇒ $a^{2} + b^{2} + c^{2} - (ab+bc+ca)=0$ Since : $a^2+b^2+c^2-ab-bc-ca = \frac{1}{2}[(a-b)^2+(b-c)^2+(c-a)^2]$ So, $a^2+b^2+c^2-ab-bc-ca = \frac{1}{2}[(a-b)^2+(b-c)^2+(c-a)^2]=0$ ⇒ $a=b=c $ So, $\frac{a+c}{b} = \frac{a+a}{a} = 2$ Hence, the correct answer is 2.
