Ans: Justin
If Tyler is hacker then tyler's first statement is false and third statement is also falls.
But according to given condition he speaks only one false statement. So Tyler is not hacker. Similarly we can see for Chandler, Paige and Shelley.
That's why Justin is hacker

You are a spy trying to gain access to a high profile building that contains very classified information. The only thing standing between you and those secrets is a keypunch security system containing the digits 1-9 that will open the door to the building. Your spy agency has provided you details about the order of the keys you need to enter:

  1. Each digit is pressed once and only once.
  2. No two consecutive digits are pressed consecutively.
  3. The digits 2 and 4 are pressed 2nd and 4th in some order; the digits 6 and 8 are pressed 6th and 8th in some order.
  4. The sum of the first 5 digits pressed is 19; the sum of the last 5 digits pressed is 27.

As you wonder why your agency couldn't just write down the sequence for you, you crack the code and enter the building.

What sequence of keys did you press on the security system to get into the building?

Madan placed a Rs2000 note on the table and left for work.

When he returned back he found that the money was gone.

There were only 3 people in his house that day: the cook, the maid and the electrician.

The cook said he put the note under a book on the table to keep it safe.

The man checked and it is no longer there.

The maid said she moved the note to the inside of the book between pages 14 and 15 while she was cleaning.

Again, the man checked the book and there was nothing between page 14 and 15.

The electrician said he saw the note sticking out of the book and he moved it between page 15 and 16 to keep it safe.
