Solution: Prime number: An integer that has two positive factors = only 1 and itself => ex) 2, 3, 5, 7…
We have to find the value of x + y
If x and y are different prime numbers greater than 30 but less than 40
Prime numbers between 30 and 40: 31 and 37 => ∴ x + y = 31 + 37 = 68
Therefore, E is the correct answer.
