What will come in the place of the question mark (?) in the following equation, if '÷' and '-' are interchanged and '×' and '+' are interchanged?
[(48−2)÷23]×19+3=?

Given expression:
[(48−2)÷23]×19+3=?
Interchanging the signs as specified:

÷↔−

×↔+

The modified equation becomes:

[(48÷2)−23]+19×3=?
Solving using the BODMAS rule:

Solve inside the innermost bracket:

48÷2=24
So, the expression becomes:

[24−23]+19×3=?
Solve the square bracket:

24−23=1
The equation is now:

1+19×3=?
Perform multiplication:

19×3=57
Perform addition:

1+57=58
Therefore, the correct answer is 58.
