SBI PO Mains 2017: Puzzle Quiz – Set 1

Directions for questions 1 to 5: Answer the questions on the basis of
the following information.

Recently, the answers of a test
held nationwide were leaked to a group of unscrupulous people. The
investigative agency has arrested the mastermind and nine other people A, B, C,
D, E, F, G, H and I in this matter. Interrogating them, the following facts
have been obtained regarding their operation. Initially the mastermind obtains
the correct answer-key. All the others create their answer-key in the following
manner. They obtain the answer-key from one or two people who already possess
the same. These people are called his/her ‘sources’. If the person has two
sources, then he/she compares the answer-keys obtained from both sources. If
the key to a question from both sources is identical, it is copied, otherwise
it is left blank. If the person has only one source, he/she copies the source’s
answers into his/her copy. Finally, each person compulsorily replaces one of
the answers (not a blank one) with a wrong answer in his/her answer key. The
paper contained 200 questions; so the investigative agency has ruled out the
possibility of two or more of them introducing wrong answers to the same
question. The investigative agency has a copy of the correct answer key and has
tabulated the following data. These data represent question numbers.
