Question

If > denote +, < denotes -, + denotes $÷$, A denotes $\times$,

- denotes =, $\times$ denotes > and = denotes < , choose the correct statement from the following questions

• A. $14>18+9=16+4>1$
• B. $4>3$ A $8<1-6+2>24$
• C. $3<6$ A $4>25=8+4>1$
• D. $12<9$ A $3<6\times 25+5>6$

Answer 1

The correct option is B $4>3$ A $8<1-6+2>24$

$14>18+9=16+4>1$

$\Rightarrow 14+18÷9<16÷4+1$

$\Rightarrow 14+2<4+1$

$\Rightarrow 16<5$ which is not true

$4>3$ A $8<1-6+2>24$
$\Rightarrow 4+3\times 8-1=6÷2+24$
$\Rightarrow 4+24-1=3+24$
$\Rightarrow 27=27$
$LHS=RHS$ which is true

$3<6$ A $4>25=8+4>1$

$\Rightarrow 3-6\times 4+25<8÷4+1$

$\Rightarrow 21+25<2+1$

$\Rightarrow 46<3$ which is not true

$12<9$ A $3<6\times 25+5>6$

$\Rightarrow 12-9\times 3-6>25÷5+6$

$\Rightarrow -21<11$ which is not true

Hence, option B is correct.
