What will come in the place of ‘?’ in the following equation, if ‘−’ and ‘×’ are interchanged and ‘+’ and ‘÷’ are interchanged? 99 + 33 − 28 × 32 ÷ 10 = ?

A62

B72

C52

D36

Answer:

A. 62

Read Explanation:

1. Interchange the Signs

Swap + with ÷
Swap - with ×

Original: 99 + 33 - 28 × 32 ÷ 10 = ?
New Equation: 99 ÷ 33 × 28 - 32 + 10 = ?

2. Solve Using BODMAS Rule

Division: 99 ÷ 33 = 3
Equation: 3 × 28 - 32 + 10
Multiplication: 3 × 28 = 84
Equation: 84 - 32 + 10
Addition / Subtraction:
84 + 10 = 94
$94 - 32 = \mathbf{62}$

The final correct answer is 62.
