Question

If 'E' stands for +, 'F' stands for –, 'M' stands for ×, 'N' stands for ÷, then 19 M 5 E 39 N 3 F 8 = ?

• A. 105
• B. 100
• C. 95
• D. 90

Hint:

Always follow the order of operations (BIDMAS/PEMDAS) to correctly evaluate mathematical expressions with multiple operations.

Answer 1

The Correct Option is B

Step 1: First, replace the letters with their respective operations: 
- M = × 
- E = + 
- N = ÷ 
- F = – 
Step 2: Now, the expression becomes: 
\[ 19 \times 5 + 39 \div 3 - 8 \] Step 3: Apply the operations in order (following BIDMAS/PEMDAS rules): 
- \( 19 \times 5 = 95 \) 
- \( 39 \div 3 = 13 \) 
So, the expression becomes: 
\[ 95 + 13 - 8 \] Step 4: Finally, calculate: 
\[ 95 + 13 = 108 \, \text{and} \, 108 - 8 = 100 \] Thus, the correct answer is (b) 100.
