Answer» Correct Answer - Option 1 : Only 1 Given: Two conditions are given Concept Used: Any number ends with zero should in the form of 2m × 5n where both m and n are positive integer Calculation: Consider the first statement, (12)n never ends with zero ∴ (12)n = (3 × 4)n = (3)n × (4)n so, (12)n never ends with zero Now, Consider the second statement, (6)n is divisible by 5 ∴ (6)n = (3 × 2)n = (3)n × (2)n ∵ (6)n never ends with zero ∴ (6)n is not divisible by 5 Hence, option (1) is correct |
