What will come in the place of ‘?’ in the following equation, if ‘+' and ‘÷’ are interchanged and ‘×' and '-' are interchanged?
21 + 3 – 7 ÷ 11×4 = ?

Given: 21 + 3 – 7 ÷ 11×4 = ? with operations interchanged.
Logic: Interchange ‘+’ and ‘÷’, and ‘×’ and ‘-’ in the equation:
21÷3×7+11−4 = ?
Following BODMAS:
21÷3×7+11−4 = ?

7×7+11−4 = ?

49+11−4 = ?

60−4 = ?

? = 56
Correct answer: (d) 56
