2 < x <= 4 : x can have two values 3 or 4
0<= x <= 3 : x can have 4 values = 0,1,2,3,
common value = 3 ; Hence only one value for X; Hence E
0<= x <= 3 : x can have 4 values = 0,1,2,3,
common value = 3 ; Hence only one value for X; Hence E

1. Given 2<x<=4; there is only two possible integers for this condition -- x=(3,4)
2. Given 0<=X<=3; x = (0,1,2,3)
3. The question stem asks for how many integers x satisfy both givens; since 3 is the only integer that overlaps both, there is only one integer x that satisfies both givens.
Ans (E) 1
