12 ÷ 6 + 28 - 7 × 14 = ?

• A. 80
• B. 72
• C. 82
• D. 78

Answer 1

Answer:

C. 82

The value that will come in place of the question mark is 82.

First, decode the mathematical operators using the given code rules:

* ÷ becomes ×

* + becomes -

* - becomes ÷

* × becomes +

## 1. Substituting the signs into the equation:

* Original: 12 ÷ 6 + 28 - 7 × 14 = ?

* Decoded: 12 × 6 - 28 ÷ 7 + 14 = ?

## 2. Solving using BODMAS rules:

* Step 1: Division (÷)

* 28 ÷ 7 = 4

* The equation becomes: 12 × 6 - 4 + 14

* Step 2: Multiplication (×)

* 12 × 6 = 72

* The equation becomes: 72 - 4 + 14

* Step 3: Addition and Subtraction (+ / -)

* 72 - 4 = 68

* 68 + 14 = 82
