Question

What will come in the place of "?' in the following equation, if 'x' and '-' are interchanged and '+' and '÷' are interchanged? 16 - 66 + 6 × 26 ÷ 36 = ?

• A. 166
• B. 186
• C. 204
• D. 241

Answer 1

Answer:

B. 186

Apply the interchange first:

• $( \times \leftrightarrow - )$

• $( + \leftrightarrow \div )$

  Original expression:

$16 - 66 + 6 \times 26 \div 36$
After interchange:

$16 \times 66 \div 6 - 26 + 36$

Now solve using BODMAS:

$16 \times 66 = 1056$
$1056 \div 6 = 176$
176 - 26 = 150
150 + 36 = 186
Final Answer:

186
