Logic Problem

Name: Anonymous 2010-09-04 12:02

A test consists of 30 true or false questions. After the test (answering all 30 questions), Victor gets his score: the number of correct answers. Victor is allowed to take the test (the
same questions ) several times. Can Victor work out a strategy that insure him to get a perfect score after the 25th attempt?

There are several outcomes dependent on chance.

If you are guessing, and you are allowed any way to answer and finish the test, but you must consider each question each time, and the questions are randomized, and you cannot understand the question, then the maximum amount of possible answers at any single instance is 265,252,859,812,191,058,636,308,480,000,000.

The maximum amount of time to ensure that it takes place, if no one is keeping track of their answer, is 70,359,079,638,545,882,374,689,246,780,656,000,000,000,000,000,000,000,000,000,000,000 attempts.

Although anyone with a lick of intelligence can solve this problem in 2 attempts.

The answer is yes.
