  • 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)         \[\frac{3}{11}\]                                                                     

    Correct Answer: B

    Solution :

    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, \[\frac{18}{11}=\frac{6}{11}+X+\frac{2}{11}+\frac{5}{11}+\frac{3}{11}\] \[\Rightarrow \]\[\frac{18}{11}=\frac{16}{11}+X\]\[\Rightarrow \]\[X=\frac{18}{11}-\frac{16}{11}=\frac{2}{11}\]
