Question

What will come in the place of '?' in the following equation, if '÷' and '-' are interchanged and 'x' and '+' are interchanged? 12 × 96 - 24 + 8 ÷ 38 = ?

• A. 16
• B. 6
• C. -4
• D. -14

Answer 1

Answer:

B. 6

Interchange the signs as given:

• (÷) and (−) are interchanged

• (×) and (+) are interchanged

So the expression becomes:
$12 + 96 ÷ 24 × 8 - 38$
Now solve using BODMAS:

$96 ÷ 24 = 4$
4 × 8 = 32

Now:

$12 + 32 - 38 = 44 - 38 = 6$

Final Answer: 6
