What will come in place of the question mark (?) in the following equation if ‘+’ and ‘×’ are interchanged and ‘−’ and ‘÷’ are interchanged?
14 − 7 × 10 ÷ 1 + 7 = ?

The correct answer is 5.

Given Equation:

$14-7\times 10÷1+7=?$

Interchange Rules:
Interchange '+' and '×'
Interchange '-' and '÷'

After interchanging the mathematical operators in the equation, we get:

$14÷7+10-1\times 7=?$

Now, follow the BODMAS rule (Brackets, Orders, Division/Multiplication, Addition/Subtraction) to simplify the equation step-by-step:

Step 1: Perform Division

$14÷7=2$

Substituting this result back into the equation gives:

$2+10-1\times 7$

Step 2: Perform Multiplication

$1\times 7=7$

Substituting this result back into the equation gives:

$2+10-7$

Step 3: Perform Addition

$2+10=12$

Substituting this result back into the equation gives:

$12-7$

Step 4: Perform Subtraction

$12-7=5$

Therefore, the value that replaces the question mark (?) in the equation is 5.
