Question

What will come in place of the question mark (?) in the following equation if '+' and '-' are interchanged and 'x' and "÷' are interchanged? 5÷6×3-4+11=?

• A. 7
• B. 11
• C. 14
• D. 3

Answer 1

Answer:

D. 3

Apply the given interchanges:

• (+) ↔ (-)

• (×) ↔ (÷)

  Transform the expression

Original:
$5 ÷ 6 × 3 - 4 + 11$

After interchange:
$5 × 6 ÷ 3 + 4 - 11$

Solve using BODMAS

$5 × 6 = 30$
$30 ÷ 3 = 10$
Now:
$10 + 4 - 11 = 3$

Final Answer: 3
