Question

What will come in the place of the question mark (?) in the following equation, if "+' and '÷' are interchanged and '-' and 'x' are interchanged? 9 - 4 × 58 + 2 ÷ 22 = ?

• A. 29
• B. 32
• C. 25
• D. 35

Answer 1

Answer:

A. 29

Interchange the operators as given:

• (+) ↔ (÷)

• (-) ↔ (×)

  Original expression:

$9 - 4 × 58 + 2 ÷ 22$

After interchange:
$9 × 4 - 58 ÷ 2 + 22$
Now solve using BODMAS:

$= 9 × 4 - 58 ÷ 2 + 22$
$= 36 - 29 + 22$
$= 7 + 22$
$= 29$

Final Answer:

29
