Tom and Jack are in a line to purchase iphones. How many people are in the line?
(1) There are 20 people behind Tom and 20 people in front of Jack.
(2) There are 5 people between Tom and Jack.
My thought is since there are 20 people behind Tom and 20 people infront of Jack, so there are 19 people between Tom and Jack.
(2) I think it is correct. Because total people would be 7.
Statement 1: There are 20 people behind Tom and 20 people in front of Jack.
This means 20 + Jack + Tom + 20 (total 42 people) or 19+Tom+Jack+19 (total 40 people).
InsufficientStatement 2:There are 5 people between Tom and Jack.
This means x+Jack+5+Tom+y (total unknown number of people)
InsufficientBoth statements put together, they're still
Insufficient since we don't know the order between Tom and Jack.
20+Jack+5+Tom+20 (total 47 people) or 14+Tom+5+Jack+14 (total 35 people).
Therefore, Correct answer is
Option E.
