If A means ‘plus’, B means ‘minus’, C means ‘divided by’ and D means ‘multiplied by’, then 18 A 12 C 6 D 2 B 5 = ?Select an answerA15B25C27DNone of these

First, let's replace the letters with the corresponding mathematical operations:

18 A 12 C 6 D 2 B 5 becomes 18 + 12 ÷ 6 * 2 - 5

Next, we perform the operations in the correct order according to the BIDMAS/BODMAS rule (Brackets, Indices/Orders, Division and Multiplication (from left to right), Addition and Subtraction (from left to right)):

First, we perform the division: 12 ÷ 6 = 2, so the equation becomes 18 + 2 * 2 - 5

Next, we perform the multiplication: 2 * 2 = 4, so the equation becomes 18 + 4 - 5

Then, we perform the addition: 18 + 4 = 22, so the equation becomes 22 - 5

Finally, we perform the subtraction: 22 - 5 = 17

So, 18 A 12 C 6 D 2 B 5 = 17. The correct answer is not listed among the options, so the answer is D: None of these.
