What will come in the place of the question mark (?) in the following equation, if '+' and '-' are interchanged and '×' and '÷' are interchanged?
(28÷4)−(15×3)+48=?

Given equation:
(28÷4)−(15×3)+48=?
Interchanging the signs as instructed:

+ becomes − and − becomes +

× becomes ÷ and ÷ becomes ×

Substituting the new signs into the equation:

(28×4)+(15÷3)−48=?
Now, solve using the BODMAS rule:

First, solve the brackets:

28×4=112
15÷3=5
So, the equation becomes:

112+5−48=?
Perform addition:

112+5=117
Perform subtraction:

117−48=69
Therefore, the correct value is 69.
