โœ“ Correct Answer: Option D Verified Solution

๐Ÿ“˜ Step-by-Step Solution & Detailed Explanation:

1. Evaluate the expression with changed operators


Step 1: Understand the operator changes

The problem defines new meanings for the standard arithmetic operators:

  • + means *
  • / means -
  • * means /
  • - means +

Step 2: Rewrite the expression with the new operators

The original expression is 4 + 11 / 5 - 5.
Applying the new operator meanings:

  • Replace + with *
  • Replace / with -
  • Replace - with +

The new expression becomes: 4 * 11 - 5 + 5

Step 3: Evaluate the new expression

Follow the order of operations (multiplication first, then addition/subtraction left to right):

  1. Multiplication: 4 * 11 = 44
  2. Subtraction: 44 - 5 = 39
  3. Addition: 39 + 5 = 44

Answer:

The value of the expression is 44.
Since 44 is not among options A, B, or C, the correct option is:
(D) None of these.
