The Correct Option is B
Solution and Explanation
Concept:
Look for a pattern relating digits of the number to the result.
Step 1: Analyze 671 : 7.
\[ 6 + 7 + 1 = 14,\quad 6 \times 1 = 6,\quad 14 - 7 = 7 \] So pattern: \[ ({sum of digits}) - ({first digit} \times {last digit}) \]
Step 2: Apply same pattern to 156.
\[ 1 + 5 + 6 = 12 \] \[ 1 \times 6 = 6 \] \[ 12 + 2 = 14 \] Thus, the required value is 14.
