What will come in the place of '?' in the following equation, if '+' and '–' are interchanged and '×' and '÷' are interchanged?
9 ÷ 576 × 24 + 109 – 7 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 114.
Given: + ⇔ – and × ⇔ ÷
After interchanging the expression becomes:
= 9 × 576 ÷ 24 - 109 + 7
= 9 × 24 - 109 + 7
= 216 - 109 + 7
= 223 - 109
= 114
