What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
25÷5–918×9+4=?

First, perform the given interchanges of the signs:
'÷' becomes '×'

'−' becomes '+'

'×' becomes '÷'

'+' becomes '−'

Rewriting the expression with the new signs:

25×5+918÷9−4
Now, solve using the BODMAS rule:

Division:

918÷9=102
The expression becomes: 25×5+102−4

Multiplication:

25×5=125
The expression becomes: 125+102−4

Addition:

125+102=227
Subtraction:

227−4=223
