What will come in the place of the question mark (?) in the following equation, if '+' and '' are interchanged and '×' and '' are interchanged?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 222.
On interchanging signs,

= 240 - 34 + 16
= 256 - 34
= 222.
