What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
1604 × 4 – 525 ÷ 5 + 73 = ?

Given: 1604 × 4 – 525 ÷ 5 + 73 = ?

Now, ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged then given equation will become

 To solve this, we follow the BODMAS rules.

=401 + 525 ×5 - 73

=401 + 2625 -73

=3026-73

Thus, the correct answer is option (c).
