What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?

26 + 43 − 32 × 23 ÷ 46 = ?​​

Given:

26 + 43 − 32 × 23 ÷ 46 = ? 

 New Equation;  26 - 43+ 32 ÷  23 × 46 = ? 

​$$? = 26 - 43+ \frac{32}{23}\times46\\ \ \\? = 26 - 43+32\times2\\ \ \\ ? = 26 - 43+64\\ \ \\? = 90 - 43\\ \ \\ ? = \bf47$$  

Thus, correct option is (a).
