• # question_answer Which number should come in place of ??' so that sum of each arm is same? A)  $\frac{6}{11}$                        B)  $\frac{2}{11}$                      C)                    $\frac{9}{11}$            D)         $\frac{3}{11}$

We have, $\frac{2}{11}+\frac{6}{11}+\frac{2}{11}+\frac{7}{11}+\frac{1}{11}=\frac{18}{11}$ Let the missing number be $X$. According to question, $\frac{18}{11}=\frac{6}{11}+X+\frac{2}{11}+\frac{5}{11}+\frac{3}{11}$ $\Rightarrow$$\frac{18}{11}=\frac{16}{11}+X$$\Rightarrow$$X=\frac{18}{11}-\frac{16}{11}=\frac{2}{11}$
