If '+' means '—', '—' means '÷', '÷' means '×' and '×' means '+', what will come in place of the question mark (?) in the following equation?

18 - 3 × 14 ÷ 2 + 12 = ?

A24

B22

C19

D21

Answer:

The value that will come in place of the question mark is 22.

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

* - becomes ÷

* × becomes +

* ÷ becomes ×

* + becomes -

## 1. Substituting the signs into the equation:

* Original: 18 - 3 × 14 ÷ 2 + 12 = ?

* Decoded: 18 ÷ 3 + 14 × 2 - 12 = ?

## 2. Solving using BODMAS rules:

* Step 1: Division (÷)

* 18 ÷ 3 = 6

* The equation becomes: 6 + 14 × 2 - 12

* Step 2: Multiplication (×)

* 14 × 2 = 28

* The equation becomes: 6 + 28 - 12

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

* 6 + 28 = 34

* 34 - 12 = 22
