Question : If $a = 101, b = 102,$ and $c =103$, then $a^{2} + b^{2} + c^{2} -ab - bc - ca$ =_____
Option 1: 2
Option 2: 4
Option 3: 3
Option 4: 6
Correct Answer: 3
Solution : $(a + b + c)^{2} = a^{2} + b^{2} + c^{2} + 2(ab + bc + ca)$ $⇒(a + b + c)^{2} -3(ab + bc + ca) = a^{2} + b^{2} + c^{2} + 2(ab + bc + ca) –3(ab + bc + ca)$ Putting
