Answer 1

BODMAS

Given: 36 ÷ 15 − 175 × 5 + 11 = ?

According to the question, after ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged:

36 ÷ 15 − 175 × 5 + 11 = ? ⇒ 36 × 15 + 175 ÷ 5 − 11 = ?

⇒ 36 × 15 + 175 ÷ 5 − 11 = ?

⇒ 36 × 15 + 35 − 11 = ?

⇒ 540 + 35 − 11 = ?

⇒ 575 − 11 = ?

⇒ 564 = ?

Hence, "Option 4" is the correct answer.
