Solving the Coded Expression

Step 1: Replace the letters with their corresponding mathematical operators

Given the coding scheme:

• 'E' stands for '+'
• 'F' stands for '-'
• 'M' stands for '×'
• 'N' stands for '÷'

The expression is:

19 M 5 E 39 N 3 F 8

Replacing the letters with the operators, we get:

19 × 5 + 39 ÷ 3 - 8

Step 2: Perform multiplication and division

Following the order of operations (BODMAS/PEMDAS):

19 × 5 = 95

39 ÷ 3 = 13



The expression now becomes:

95 + 13 - 8

Step 3: Perform addition and subtraction

95 + 13 = 108

108 - 8 = 100

Answer:

The correct answer is (B) 100.
