Select the correct equation after interchanging the operators ‘$$-$$’ and ‘$$\times$$’ and the numbers ‘4’ and ‘3’.

We check  to interchange the operators ‘$$-$$’ and ‘$$\times$$’ and the numbers ‘4’ and ‘3’

we check (A)$$9-4\times 3=21 $$

interchange  ‘$$-$$’ and ‘$$\times$$’ and the numbers ‘4’ and ‘3’

$$9\times 3- 4 = 21 $$

From LHS $$9\times 3- 4$$

$$\Rightarrow 27 - 4 $$

$$\Rightarrow 23 $$ RHS it is not satisfied.

we check option (B) $$4-3\times 9= 3 $$

Interchange ‘$$-$$’ and ‘$$\times$$’ and the numbers ‘4’ and ‘3’

$$ 3\times 4 - 9 = 3 $$

From LHS $$ 3\times 4 - 9 $$

$$\Rightarrow 12 -9 $$

$$\Rightarrow 3 $$ RHS it is satisfied .

therefore (B) Ans
