Given equation: 36 × 104 − 13 + 8 ÷ 38 = ?

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

36 × 104 − 13 + 8 ÷ 38 = ? ⇒ 36 + 104 ÷ 13 × 8 - 38 = ?

⇒ 36 + 104 ÷ 13 × 8 - 38 = ?

⇒ 36 + 8 × 8 - 38 = ?

⇒ 36 + 64 - 38 = ?

100 - 38 = ?

⇒ 62 = ?

Hence, "Option 1" is the correct answer.
