Question

Select the number that will come in the place of the question mark (?), if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged in the expression:

121 × 11 – 28 ÷ 3 + 17 = ?

Accepted Answer

Step 1: Interchange the operators as per the instruction:  
- '+' and '–' are interchanged  
- '×' and '÷' are interchanged

Original expression:  
121 × 11 – 28 ÷ 3 + 17

After interchange:  
121 ÷ 11 + 28 × 3 – 17

Step 2: Evaluate the expression following BODMAS:  
 
First, division and multiplication from left to right:  
121 ÷ 11 = 11  
28 × 3 = 84

Expression becomes:  
11 + 84 – 17

Step 3: Perform addition and subtraction from left to right:  
11 + 84 = 95  
95 – 17 = 78

Re-check:  
121 ÷ 11 = 11  
28 × 3 = 84  
11 + 84 = 95  
95 – 17 = 78

The answer is 78.

Step 5: Check options again:  
Options are 85, 91, 78, 64  
78 is option 3.

Correction: The correct answer is 78.

Final answer: 78
