The value of the expression (15 * 6) / 3 + 24 - 12 is:
42
38
40
36
42
To evaluate the expression, follow the BODMAS rule: first compute the operation inside the parentheses (15 multiplied by 6 is 90), then perform division (90 divided by 3 is 30), followed by addition (30 plus 24 is 54), and finally subtraction (54 minus 12 is 42). Thus, the final value of the expression is 42.

Thus, the final value of the expression is 42.
In competitive examinations like RRB JE and SSC CGL, quantitative reasoning and mathematical operations follow strict hierarchical rules known globally as BODMAS, ensuring standardized evaluation of arithmetic expressions.
BODMAS rule dictates the order of operations: Brackets, Orders, Division, Multiplication, Addition, and Subtraction.
Multiplication and Division have equal priority and are evaluated sequentially from left to right.
Addition and Subtraction have equal priority and are evaluated sequentially from left to right.
Step 1: Parentheses evaluation yields 15 multiplied by 6 equal to 90.
Step 2: Division yields 90 divided by 3 equal to 30.
Step 3: Addition yields 30 plus 24 equal to 54.
Step 4: Subtraction yields 54 minus 12 equal to 42, matching Option A.
A is correct тАФ evaluating the expression using the BODMAS rule yields 42.
Mastering the BODMAS rule is essential not only for basic simplification questions but also for solving complex data interpretation and algebraic expression problems in railway and banking exams.
