Detailed Solution
Download Solution PDFGiven equation: 55 ÷ 25 – 5 + 15 × 10 = ?
After interchanging ‘−’ and ‘÷’ and ‘×’ and ‘+’, the equation becomes:
55 − 25 ÷ 5 × 15 + 10 = ?
According to BODMAS rule:
⇒ 55 − 25 ÷ 5 × 15 + 10 = ?
⇒ 55 − 5 × 15 + 10 = ?
⇒ 55 − 75 + 10 = ?
⇒ −20 + 10 = −10
Hence, the correct answer is "Option 1"
