Choose the correct choice from the following choices.
A) 50
B) 51
C) 52
D) 53
E) 54

Rationale: "this is an example of a standard overlapping sets question . it has no ' twists ' to it , so you ' ll likely find using the overlapping sets formula to be a fairly easy approach . if you ' re not familiar with it , then here is the formula : 90 = 55 + 33 - 51 + ( # in neither group ) = 53 the prompt gives you all of the numbers you need to get to the correct answer . just plug in and solve . d"
Answer: D
