Ifkis a positive integer, iska prime number??1)kcan be written as 6n+ ...
The answer is wrong here I guess
bkz in statement 1 k can be 7 or be 25
one is prime another is not.
statement 2 says k>24,so k can be 29 or be 30
again Not sufficient
combining k can be 25 or 31
again not sufficient
answer should be E

Ifkis a positive integer, iska prime number??1)kcan be written as 6n+ ...
Statement 1:k can be written as 6n + 1, where n is a positive integer.
When n = 1: 6n + 1 = 7 which is a prime number
When n = 4: 6n + 1 = 25 which is not a prime number
Therefore Statement 1 Alone is Insufficient. Answer options could be B, C or E
Statement 2: k > 4! or k > 24
Her we can have multiple values. If k = 25, it is not prime and if k = 29 it is prime.
Therefore Statement 2 Alone is Insufficient.
Combining Both Statements:
k = 6n + 1 and k > 24
When n = 4: k = 6n + 1 = 25 which is not a prime number
When n = 5: k = 6n + 1 = 31 which is a prime number
Therefore Both Statements together are Insufficient.
When n = 1: 6n + 1 = 7 which is a prime number
When n = 4: 6n + 1 = 25 which is not a prime number
Therefore Statement 1 Alone is Insufficient. Answer options could be B, C or E
Statement 2: k > 4! or k > 24
Her we can have multiple values. If k = 25, it is not prime and if k = 29 it is prime.
Therefore Statement 2 Alone is Insufficient.
Combining Both Statements:
k = 6n + 1 and k > 24
When n = 4: k = 6n + 1 = 25 which is not a prime number
When n = 5: k = 6n + 1 = 31 which is a prime number
Therefore Both Statements together are Insufficient.
