The correct answer is Option A: 19. Apply BODMAS: First convert letters to symbols (M=/, K=*, N=+, L=-), then follow Division -> Multiplication -> Addition -> Subtraction order.

Step-by-Step Solution & Concepts:
Shortcut Trick: Apply BODMAS: First convert letters to symbols (M=/, K=*, N=+, L=-), then follow Division -> Multiplication -> Addition -> Subtraction order.

Steps: Substitution: Replace letters with symbols given in the problem: 9 M 3 K 13 N 3 L 23 becomes 9 / 3 * 13 + 3 - 23.. Applying BODMAS: Divide: 9 / 3 = 3. Multiply: 3 * 13 = 39. Add: 39 + 3 = 42. Subtract: 42 - 23 = 19.

Answer: A is correct because applying the BODMAS order of operations (Division, Multiplication, Addition, Subtraction) to the expression 9 / 3 * 13 + 3 - 23 yields the result 19.

Why options are wrong: B: 24 is incorrect as it results from miscalculating the order of operations. C: 14 is incorrect. D: 29 is incorrect.

Exam Tip: Always perform division before multiplication in these problems to avoid common errors; most candidates fail because they multiply before dividing.
