Question

If, \( 553 @ 1 = 7 \), \( 652 @ 2 = 6 \), then \( 1 @ 3 = ? \)

• A. 0
• B. 1
• C. 2
• D. 3

Hint:

Check for patterns based on simple operations like addition or subtraction of digits in similar number puzzles.

Answer 1

The Correct Option is A

The pattern in the given questions suggests that the operation "@", involves the difference between the digits, for example: \[ 553 @ 1 \rightarrow |5 - 5| + 3 - 1 = 7. \] Similarly: \[ 652 @ 2 \rightarrow |6 - 5| + 2 - 2 = 6. \] For \( 1 @ 3 \): \[ 1 @ 3 \rightarrow |1 - 0| + 3 - 3 = 0. \] Final Answer: \[ \boxed{0} \]
