Asked: What is the value of positive integer x?
1) x has precisely three distinct prime divisors.
If x = 30 = 2*3*5; x has precisely three distinct prime divisors.
But if x = 105 = 3*5*7; x has precisely three distinct prime divisors.
NOT SUFFICIENT
2) 100 < x < 110
x = {101,102,103,104,105,106,107,108,109}
NOT SUFFICIENT
(1) + (2)
1) x has precisely three distinct prime divisors.
2) 100 < x < 110
If x = 3*5*7 = 105; x has precisely three distinct prime divisors.
But if x = 102
