• A. $12$
• B. $16$
• C. $18$
• D. $24$

Answer 1

The correct option is B $16$

$\Rightarrow$ Here, $16÷64-8\times 4+2$

$\Rightarrow$ We have given, ${}^{\prime }{+}^{\prime }$ means $X,$ ${}^{\prime }{-}^{\prime }$ means ${}^{\prime }{÷}^{\prime }$, ${}^{\prime }{X}^{\prime }$ means ${}^{\prime }{-}^{\prime }$ and ${}^{\prime }{÷}^{\prime }$ means $+$.

$\therefore$ $16+64÷8-4\times 2$

$\Rightarrow$ $16+8-8$

$\Rightarrow$ $16-0$

$\Rightarrow$ $16$
