# SBI PO Mains 2017: Puzzle Quiz – Set 1

Hello and welcome to exampundit. Here is the first Puzzle for SBI PO Mains 2017.

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
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.

Answers & Solutions – Tap to show
If a person copies from one source, he must have the same
blank answers as the source and exactly one wrong answer more than the source
(as the copier has introduced one wrong answer on his own). If the person
copies from two sources, the distinct wrong answers from the two sources would
be left blank by the copier and the same wrong answers in the two sources would
be copied as it is.
1. 2 A and D have only one source since they have only one
wrong answer each. C may have copied from only one source i.e. I and hence,
only B has two sources.
2. 3 I did it before C since 27 is the wrong choice for I.
Similarly, A, D and E made keys before C. Hence, 4 people made their keys
before C.
3. 4 Both G and H can’t be sources to any of F, B or I and
hence, (4) is the correct option.
4. 3 F introduced wrong answer to question 14, because
nobody else has done question 14 wrong.
5. 4 A, D and G have one distinct wrong answer and no blank
answers. So they must have the same source. E and H also have a common wrong
For questions 6 to 9:
The key to cracking this question is to follow the simple
fundamentals in Analytical Reasoning of going 1 line at a time and making a
simple table
 Arrival Order Husband Wife Kids 1 Joya 2 2 Shanthi 0 3 Sridevi 4 Sunil 1
Sentence 1 – Family with 2 kids before no kids
Sentence 2 – Shanthi with no kids came before Sridevi
Sentence 3 – Sunil and wife came last with only kid
Sentence 4 – Anil and Joya not husband and wife
Sentence 5 – Anil and Raj are fathers – hence cannot be the
family with no kids
Sentence 6 – Sridevi and Anita cannot be the persons with no
kid
Sentence 7 – Anil and Joya not husband and wife
Sentence 8 – Joya before Shanti and Anita was already present.
Using the above information, Anil and Raj cannot be married
to Shanthi as Shanthi has no kids. Hence,
Sunil has to be married to Sridevi (not with Joya already
stated) and Raman with Shanthi.
