Directions: In each question below is given a statement followed by two inferences numbered I and II. An inference is something that can be deduced or found out on the basis of the given facts. You have to consider the statement and the following inferences and decide which of them is implicit from the statement.
1) Statement: In many parts of the world the majority of bank customers regularly use Automatic Teller Machines (ATMs) and today’s western youth have not known a world without them. For them, the prevailing Perception of a cash machine is that of a tool providing a familiar functionality of basic financial information and dispensing cash.
Inference:
I. The plastic card is replacing cheque and personal attendance of the customer
II. It has taken approximately 30 years to establish ATMs as ubiquitous examples of public walkup and-use devices
A. if only inference I is implicit.
B. if only inference II is implicit
C. if either I or II is implicit
D. if neither I nor II is implicit
E. if both I and II are implicit.
Sol:
When we read the following lines in the
paragraph -> ‘today’s western youth have not
known a world without them’ can be used to infer
that things like cheques etc have now been
replaced by ATMs. So, statement (I) follows.
Statement (II) however, gives different
information which cannot be called as an
inference because an inference is drawn based
on the facts in the statement and nothing of the
sort mentioned in (II) has been given in the
same.
2) If all the even digits are changed to the next digit whereas all odd digits are changed to the previous digit in the number series, then all the digits are rearranged in ascending order from left to right. Which of the following numbers the positions of two or more digits remain unchanged?
I. 3574826
II. 4857923
III. 5986432
A. Both I and III
B. Only II
C. Both I and II
D. Only I
E. None of these
Sol:
From I: 3574826 → 2465937 → 2345679 (no digit
remains unchanged)
From II: 4857923 → 5946832 → 2345689 (no
digit remains unchanged)
From III: 5986432 → 4897523 → 2345789 (no
digit remains unchanged)
Hence, option E is the correct choice.
