What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
- A16
- B25
- C20
- D32
Solution & Step-by-step Explanation
Given original equation: Interchanging the signs:‘+’ becomes ‘–’ and vice versa.‘×’ becomes ‘÷’ and vice versa.Substituting the new operators into the expression:
Now solving step-by-step using BODMAS rules:First, evaluate operations inside parentheses: The expression becomes: Addition: Subtraction: Thus, the answer is .
