x, y and z are prime numbers and x + y + z = 38. What is the maximum value of x?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 31
x + y + z = 38
The maximum possible value of x can be either 31 or 37 but as y and z are also prime numbers and y + z ≠ 1,
Thus, x = 31
