Question:


If ‘÷’ means ‘addition’, ‘+’ means ‘subtraction’, ‘–’ means ‘multiplication’ and ‘×’ means ‘division’, then the value of 18÷12×4 – 5 is 

    (A) 25 

    (B) 35 

    (C) 40 

    (D) 33


Solution:


Let's first replace the symbols according to the given meanings:

  • ‘÷’ means ‘addition’: 18 ÷ 12 becomes 18 + 12

  • ‘+’ means ‘subtraction’: (Not used in this problem)

  • ‘–’ means ‘multiplication’: 4 – 5 becomes 4 × 5

  • ‘×’ means ‘division’: 12 × 4 becomes 12 ÷ 4

Now, rewrite the expression with the new operations:

18+12÷4×5

Next, apply the correct order of operations (BODMAS):

  1. Division first: 12÷4=3

  2. Multiplication next: 3×5=15

  3. Addition: 18+15=33

The correct answer is (D) 33.
