What will come in the place of the question mark (?) in the following equation, if '+' and '-' are interchanged and 'x' and '÷' are interchanged? 2 ÷ 70 x 2 - 30 + 30 = ?

A69

B68

C70

D66

Answer:

C. 70

Read Explanation:

Interchange the operators:

  • (+) ↔ (-)

  • (×) ↔ (÷)

So the expression becomes:
2 × 70 ÷ 2 + 30 - 30

Apply BODMAS:

2 × 70 = 140
140 ÷ 2 = 70
70 + 30 - 30 = 70

Final Answer:

70
