Question

What will come in the place of the question mark (?) in the following equation if '+' and '-' are interchanged and 'x' and '> are interchanged? 60 + 9÷63 - 72 × 12 = ?

• A. -501
• B. -503
• C. -502
• D. -504

Answer 1

Answer:

A. -501

Interchange the operators:

• (+) ↔ (−)

• (×) ↔ (÷)

  Given expression:

$60 + 9 ÷ 63 - 72 × 12$
After interchange:

$60 - 9 × 63 + 72 ÷ 12$
Now solve using BODMAS:

$9 × 63 = 567$

$72 ÷ 12 = 6$

So:
$60 - 567 + 6$
$60 - 567 = -507$
$-507 + 6 = -501$
Final Answer: -501
