What will come in the place of ‘?’ in the following equation, if ‘÷’ and ‘–‘ are interchanged and ‘×’ and ‘+’ are interchanged?
15 × 9 + 7÷ 26 – 13 = ?

Correct option is C

Given the equation:
15×9+7÷26–13=?

Interchanges:
‘÷’ and ‘–’ are interchanged
‘×’ and ‘+’ are interchanged
Step 1: Replace the Operators
Thus, the equation becomes:
15+9×7−26÷13=?
Apply BODMAS Rule
We will solve the equation step by step using BODMAS (Brackets, Orders, Division, Multiplication, Addition, Subtraction).
Multiplication first:
9×7=63
Division next:
26÷13=2
Addition next:
15+63=78
Subtraction last:
78−2=76
Find the Correct Answer
Thus, the missing number? is 76.
The correct answer is:
(C) 76
