Which of the following is a prime number ?
A. 115
B. 119
C. 127
D. None of these
Answer: Option C
Solution (By Examveda Team)
We know that 115 is divisible by 5, so it is not prime.119 is divisible by 7, so it is not prime.
127 < (12)2 and prime numbers less than 12 are 2, 3, 5, 7, 11.
Clearly, 127 is not exactly divisible by any of them.
Hence, 127 is a prime number.
