    If \['\Rightarrow '~\]stands for'+' \['\Uparrow '~\] stands for \[\,'\div ',~\]\['\Downarrow '~\] stands for \['\times ',\text{ }'\Leftarrow '\]stands for \['-'\]and \['\otimes '\]stands for '=', then which of the following statements is correct?

    A) \[5\Rightarrow 7\Leftarrow 2\Downarrow 3\Uparrow 5\text{ }\otimes 10\]                              

    B) \[2\Downarrow 5\Leftarrow 6\Rightarrow 2\otimes 6\]

    C) \[2\Downarrow 6\Uparrow 4\Leftarrow 3\Rightarrow 7\otimes 0\]                              

    D) \[5\Rightarrow 7\Leftarrow 3\Uparrow 2\otimes 4\]

    Correct Answer: B

    Solution :

     : \[2\Downarrow 5\Leftarrow 6\Rightarrow 2\otimes 6=2\times 5-6+2\]= 6 i.e., 6=6 which is true.
