Question

If 'A' means '+', 'B' means '–', 'C' means '×', and 'D' means '÷', then what is the value of \(18 \, C \, 14 \, A \, 6 \, B \, 16 \, D \, 4\)?

• A. \(236\)
• B. \(244\)
• C. \(248\)
• D. \(250\)

Hint:

In symbol substitution problems, always first convert the symbols into their actual operations and then apply the BODMAS rule to evaluate the expression correctly.

Answer 1

The Correct Option is A

Concept: In symbolic operation questions, first replace the symbols with their actual mathematical operations and then solve the expression using the BODMAS rule (Bracket, Order, Division, Multiplication, Addition, Subtraction). Given: \[ A = +,\quad B = -,\quad C = \times,\quad D = \div \]
Step 1:Replace the symbols with the corresponding operations.
\[ 18 \times 14 + 6 - 16 \div 4 \]
Step 2:Apply the BODMAS rule (perform multiplication and division first).
\[ 18 \times 14 = 252 \] \[ 16 \div 4 = 4 \] So the expression becomes: \[ 252 + 6 - 4 \]
Step 3:Perform addition and subtraction.
\[ 252 + 6 = 258 \] \[ 258 - 4 = 254 \] Thus, the value of the expression is: \[ 254 \]
