'$$+$$' means '$$\div$$' , '$$-$$ ' means '$$+$$', '$$\times$$' means'$$-$$' , '$$\div$$', means '$$\times$$', then what will come in place of the question mark (?) in the following equation?
$$49 - 6 \div 4 + 2 \times 14 =$$ ?

The symbols in the question do not have their usual meanings. According to the given code:

$$+ \;\to\; \div, \qquad - \;\to\; +, \qquad \times \;\to\; -, \qquad \div \;\to\; \times$$

Rewrite the given expression $$49 - 6 \div 4 + 2 \times 14$$ by replacing every symbol with its coded meaning:

$$49\;-\;\;6\;\div\;4\;+\;2\;\times\;14$$ becomes
$$49\;+\;\;6\;\times\;4\;\div\;2\;-\;14$$

Now evaluate using the ordinary order of operations (multiplication & division before addition & subtraction, proceeding left to right within the same rank).

Step 1: $$6 \times 4 = 24$$
Step 2: $$24 \div 2 = 12$$

The expression is now $$49 + 12 - 14$$.

Step 3: $$49 + 12 = 61$$
Step 4: $$61 - 14 = 47$$

Hence the value of the coded expression is 47.

Option A which is: 47
