Detailed Solution
Download Solution PDFGiven: 66 ÷ 8 − 231 × 11 + 14 = ?
According to the question, after ‘+’ and ‘–’ are interchanged, and ‘×’ and ‘÷’ are interchanged:
66 ÷ 8 − 231 × 11 + 14 = ? ⇒ 66 × 8 + 231 ÷ 11 – 14 = ?
⇒ 66 × 8 + 231 ÷ 11 – 14 = ?
⇒ 66 × 8 + 21 – 14 = ?
⇒ 528 + 21 – 14 = ?
⇒ 549 – 14 = ?
⇒ 535 = ?
Hence, "Option 4" is the correct answer.
