What will come in the place of question mark (?) in the following equation if '+' and '-' are interchanged and '×' and '÷' are interchanged?
58 - (17 ÷ 6) + (322 × 23) = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 146.
On interchanging signs,
= 58 + 17 × 6 - (322 ÷ 23)
= 58 + (17 × 6) - 14
= (58 + 102) - 14
= 160 - 14
= 146
