Question

What will come in the place of ‘?’ in the following equation, if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged? 32 – 24 + 18 ÷ 36 × 12 = ?

• A. 2
• B. -3
• C. -13
• D. -8

Answer 1

Answer:

A. 2

* '–' becomes '+'

* '+' becomes '–'

* '÷' becomes '×'

* '×' becomes '÷'

$32 + 24 - 18 \times 36 \div 12 = ?$

1. Division ($\div$):

$36 \div 12 = 3$

The equation becomes: $32 + 24 - 18 \times 3$

2. Multiplication ($\times$):

$18 \times 3 = 54$

The equation becomes: $32 + 24 - 54$

3. Addition (+):

$32 + 24 = 56$

The equation becomes: $56 - 54$

4. Subtraction (-):

$56 - 54 = 2$

The value that will come in place of the question mark is 2.
