If ‘@’ means ‘addition’, ‘%’ means ‚multiplication’, ‘$’ means ‘division‘ and ‘#’ means ‘subtraction’, then find the value of the given expression. 29 @ 128 $ 16 % 7 # 22

The correct option is 63.

To find the value of the given expression, we first need to substitute the symbols with their corresponding mathematical operations as defined:

• ‘@’ means addition (+)
• ‘$’ means division (/)
• ‘%’ means multiplication (*)
• ‘#’ means subtraction (-)

Let's write down the original expression:

$29@128\$16\%7\#22$

Now, we substitute the symbol operators with mathematical operations:

$29+128/16\times 7-22$

According to the BODMAS rule (order of operations: Brackets, Orders, Division/Multiplication, Addition/Subtraction), we perform division and multiplication first, from left to right, followed by addition and subtraction.

Step 1: Perform the Division ($)
Divide 128 by 16:

$128/16=8$

Substitute this back into the expression:

$29+8\times 7-22$

Step 2: Perform the Multiplication (%)
Multiply 8 by 7:

$8\times 7=56$

Substitute this back into the expression:

$29+56-22$

Step 3: Perform the Addition (@)
Add 29 and 56:

$29+56=85$

Substitute this back into the expression:

$85-22$

Step 4: Perform the Subtraction (#)
Subtract 22 from 85:

$85-22=63$

Therefore, the final value of the expression is 63.
