What will come in the place of ‘?’ in the following equation, if ‘+’ and ‘–’ are interchanged and also ‘×’ and ‘÷’ are interchanged?
53 – 48 × 6 ÷ 9 + 11 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 114.
53 – 48 × 6 ÷ 9 + 11 = ?
After interchanging signs,
= 53 + (48 ÷ 6) × 9 - 11
= 53 + 8 × 9 - 11
= 53 + 72 - 11
= 125 - 11 = 114
