Question

If '+' means 'divided by', '-' means 'add', ' ' means 'minus' and '/' means 'multiplied by', what will be the value of the following expression?
\(\{(17\ 12) - (4/2)\ + (23 - 6)\)/0}

• A. infinite
• B. \(0\)
• C. \(118\)
• D. \(219\)

Hint:

In coded operation questions, first replace every symbol according to the given rule, then evaluate using normal arithmetic.

Answer 1

The Correct Option is B

Concept:
This is a coded mathematical operation question. We must replace each symbol with its given meaning and then simplify the expression carefully. The given meanings are: \[ + \Rightarrow \div \] \[ - \Rightarrow + \] \[ \text{blank space} \Rightarrow - \] \[ / \Rightarrow \times \]

Step 1: Evaluate \((17\ 12)\).
Here, the blank space between \(17\) and \(12\) means minus. So: \[ (17\ 12)=17-12 \] \[ =5 \]

Step 2: Evaluate \((4/2)\).
Here, \(/\) means multiplied by. So: \[ (4/2)=4\times2 \] \[ =8 \]

Step 3: Evaluate the first bracket.
The first bracket is: \[ \{(17\ 12)-(4/2)\} \] Since \(-\) means add: \[ =5+8 \] \[ =13 \]

Step 4: Evaluate \((23-6)\).
Again, \(-\) means add. So: \[ (23-6)=23+6 \] \[ =29 \]

Step 5: Evaluate the remaining expression.
The expression becomes: \[ 13+29/0 \] But according to the code: \[ + \Rightarrow \div \] and: \[ / \Rightarrow \times \] So: \[ 13+29/0=\frac{13}{29}\times0 \] \[ =0 \]

Step 6: Check the options.
Option (A) infinite is incorrect because after symbol replacement, it is not division by zero.
Option (B) \(0\) is correct.
Option (C) \(118\) is incorrect.
Option (D) \(219\) is incorrect. Hence, the correct answer is: \[ \boxed{(B)\ 0} \]
