If $ means 'divided by'; @ means 'multiplied by'; # means 'minus', then the value of 10#5@1$5 is

Question

Accepted Answer

The problem requires substituting given symbols with mathematical operations and then evaluating the expression following the order of operations (BODMAS/PEMDAS).

1.  Identify the symbol meanings:
    $ means 'divided by' (/)
    @ means 'multiplied by' (*)
    # means 'minus' (-)

2.  Substitute these operations into the given expression:
    10 # 5 @ 1 $ 5 becomes
    10 - 5 * 1 / 5

3.  Evaluate the expression following BODMAS/PEMDAS (Brackets, Orders, Division/Multiplication, Addition/Subtraction). Multiplication and Division have equal precedence and are performed from left to right before Subtraction.

First, perform multiplication:
    5 * 1 = 5
    The expression becomes: 10 - 5 / 5

Next, perform division:
    5 / 5 = 1
    The expression becomes: 10 - 1

Finally, perform subtraction:
    10 - 1 = 9

4.  Compare the result with the options:
    The calculated value is 9, which matches option D.

Therefore, the value of 10#5@1$5 is 9.

The final answer is D.
