Question

In this question,
‘$\Delta$’ means “Greater than”
‘$\square$’ means “Less than”
‘$\varphi$’ means “equal to”
‘$\theta$’ means “not equal to”

If $C\Delta A,A\square B,D\varphi B\text{and}B\theta C$, then choose the correct option in the following.

• A. $D\square C$
• B. $D\Delta C$
• C. $D\Delta A$
• D. $B\theta D$

Answer 1

The correct option is C $D\Delta A$

Writing in standard form,
$C>A$
$A<B$
$D=B$
$B\ne C$

From this, we can conclude that A is the smallest of all.
Correct option is:
$D>A$
$D\Delta A$
