Question

Let

$\times$ : Stands for $=$
$<$ : Stands for $\ne$

$-$ : Stands for $>$
$+$ : Stands for $\ngtr$
$>$ : Stands for $<$
$=$ : Stands for $\nless$,

then $p+q-r$ can not be written as

• A. $p\times q=r$
• B. $p+q<r$
• C. $p=q=r$
• D. $p-q-r$

Answer 1

The correct option is D $p-q-r$

$p+q-r$ stands $p\ngtr q>r$ or $p\le q>r$

A.

$p\times q=r$ stands for $p=q\nless r$ or $p=q\ge r$ Possible

B.

$p+q<r$ stands for $p\le q>r$ or $p\le q<r$ Possible

C.

$p=q=r$ stands for $p\ge q\ge r$ Possible

D.

$p-q-r$ stands $p>q>r$ Not Possible

So, option D is correct.
