  • T's birthday is immediately after V's birthday.

We get,

Now,

  • At least two persons have birthdays between P's and S's birthday, which is immediately before/after of neither Q's nor U's birthday.

Thus,
Case II and case IV(a) become invalid.
Also, case V(a) and case V(b) become invalid as P's and S's birthdays cannot be consecutive.
We get,

Now, we do not know the exact date of birthdays but, it is given that, birthdays are in consecutive dates.
And, we know,

  • Q's birthday is some day between 17th January and 21st January (both exclusive).

Thus, Q's birthday can be on 18th, 19th or 20th.
But,
it is given that,

  • W's birthday is on even numbered date.

And, since two persons have birthday between Q and W, who has birthday on even date and, after Q, so it is only possible when Q has birthday on odd numbered date.
Thus, Q has birthday on 19th January.
We get,

And,

Here, it is given,

  • V's birthday is on odd numbered date.

Thus, case I(a) becomes invalid.

  • V's birthday is not a prime number.

Thus, case III and case IV(b) become invalid.

 C was 2nd to the left of F who was seated facing inside the centre

  • F was seated neighbouring B
  • B was 3rd to the right of G who was aged 63 years. Thus, G must be seated at one of the sides. Thus, cases 1 and 3 become invalid.
  • A was to the immediate right of H who was at a gap of 2 from F
  • The one who was 60 years old was seated opposite to H
  • D was 2nd to the left of E who was neighbouring G and the one who was 21 years old

  • The one who was 60 years old was seated opposite to H
  • D was 2nd to the left of E who was neighbouring G and the one who was 21 years old
  • F was 4 years younger to D. Thus, in case 3 F cannot be 21 years old, as D cannot be 25 years old.

    Case 1 and 4 are invalid as D cannot be placed 2nd to the left of E.
  • The one who was 36 years old was to the immediate left of the one who was 56 years old

    Thus, case 2 becomes invalid.
  • The one who was 24 years old was 3rd to the left of the one who was 49years old
  • B was aged twice that of H. H must be 18 years old.
  • G's neighbours were seated facing the same direction. D must be seated facing inside the centre. Hence A and B will be seated facing outside the centre.

Directions [Set of 4 questions]: Study the following information carefully and answer the questions given below:
In a certain code language following statements are coded:

  • "Road Safety Given Priority" is coded as "mj gd rs zf".
  • "People Learn Better Road Manual" is coded as "js fz bm gd sf".
  • "Priority Must Given Safety Manual" is coded as "zf rd rs mj sf".
  • "Always Follow Safety Rules" is coded as "yr dg mj gz".
  • "People Learn Traffic Rules" is coded as "js fz hd gz".

Q. Code of which of the following statements is/are required to find code of "Learn" in given code language?
(i) Always Given Learn Safety
(ii) People Must Learn Safety
(iii) Priority Must Given People
(iv) Traffic Rule Must Learn
Detailed Solution for EPFO Assistant Mains Mock Test - 1 - Question 7

We have:

  • "Road Safety Given Priority" is coded as "mj gd rs zf".
  • "People Learn Better Road Manual" is coded as "js fz bm gd sf".
  • "Priority Must Given Safety Manual" is coded as "zf rd rs mj sf".
  • "Always Follow Safety Rules" is coded as "yr dg mj gz".
  • "People Learn Traffic Rules" is coded as "js fz hd gz".

We can decode above statements as follow:

  • "Road Safety Given Priority" ------ "mj gd rs zf".
  • "People Learn Better Road Manual" ------- "js fz bm gd sf".
  • "Priority Must Given Safety Manual" ------- "zf rd rs mj sf".

From above given three statements we get:
Safety/Priority/Given → mj/zf/rs (not necessary in same order)

  • Manual → sf
  • Must → rd
  • Road → gd
  • People/Learn/Better → js/fz/bm (not necessary in same order)
  • After combining above results with remaining statements we get:
  • Safety/Priority/Given → mj/zf/rs (not necessary in same order)
  • Manual → sf
  • Must → rd
  • Road → gd
  • People/Learn/Better → js/fz/bm (not necessary in same order)
  • "Always Follow Safety Rules" ------ "yr dg mj gz".
  • "People Learn Traffic Rules" ------- "js fz hd gz".

After decoding above statements we get:

  • Manual → sf
  • Must → rd
  • Road → gd
  • Safety → mj
  • Rules → gz
  • People/Learn → js/fz (not necessary in same order)
  • Better → bm
  • Traffic → hd
  • Priority/Given → zf/rs (not necessary in same order)
  • Always/Follow → yr/dg (not necessary in same order)

We have:
People/Learn → js/fz (not necessary in same order)
To find code of "Learn" code of either "People" or "Learn" is required.
From (i) we have:
Always Given Learn Safety
We also have:
People/Learn → js/fz (not necessary in same order)
From this we get code of "Learn".
Thus, code of "Learn" can be determined.
From (ii) we have:
People Must Learn Safety
We also have:
People/Learn → js/fz (not necessary in same order)
From this we get code of "People Learn".
Thus, code of "Learn" can't be determined uniquely.
From (iii) we have:
Priority Must Given People
We also have:
People/Learn → js/fz (not necessary in same order)
From this we get code of "People".
Thus, code of "Learn" can be determined.
From (iv) we have:
Traffic Rule Must Learn
We also have:
People/Learn → js/fz (not necessary in same order)
From this we get code of "Learn".
Thus, code of "Learn" can be determined.
Hence, code of "Learn" can be determined from either 1 or 3 or 4 alone.

In each of the questions below, a statement is given followed by two situations which may or may not be a cause or effect of the event described in the statement. The situation(s) may also be neutral. From the given options choose the one that depicts the correct relationship between the statement and the situations.
Statement: International palaeontologists fear that a growing trend for the private sale of fossils is driving up prices, putting potentially valuable specimens beyond the reach of cash-strapped museums and public institutions.
Situation I: A lot of museums are on the verge of shutting down as less and less people visit them.
Situation II: Apart from Public Institutions, fossils can now also be seen in private institutions or at people's homes and offices.
Detailed Solution for EPFO Assistant Mains Mock Test - 1 - Question 9

The statement mentions that the private sale of fossils is making their prices higher for museums and public institutions to buy them. I is a probable effect as the museums are already cash strapped and in the absence of potentially valuable specimens, people wouldn't want to visit them. II is also a probable effect as the fossils are up for private sales, which makes it probable for them to be displayed in places other than museums or public institutions. Option (e) is the correct choice.

Five boxes namely, A, B, C, D and E which have different colors namely, Red, Green, White, Pink and Blue are kept one over the other from bottom to top numbered 1 to 5 such that the box at the bottom is considered at 1st position and the box at the top is considered at 5th position. What is the color of box D?
I. Only one box kept between the box A and the box which is Green color. Box A is above the Green box. Green box is not kept at 1st position. Box B which is Blue color is just above box E, which is not colored in Green.
II. Only one box kept between the Red box and the Green box. The White box is not at the 1st position. Box D is kept one of the positions above box C. Box E is not in Red color.
Detailed Solution for EPFO Assistant Mains Mock Test - 1 - Question 30

From I,
Case 1:

  • Box B which is Blue color is just above box E, which is not colored in Green. From this is not possible so this case gets rejected.

Case 2:

  • Box B which is Blue color is just above box E, which is not colored in Green. B must be at 2nd position and E must be at 1st position.
  • But we can't determine the position of D so this statement alone is not sufficient.

From II,
As we can see that alone II is not sufficient.
From I and II,
Take case 2:

  • Only one box kept between the Red box and the Green box. Box E is not in Red color. So Box A must be Red in color. The White box is not at the 1st position. So White colored box is at the 4th position. Box D is kept one of the positions above box C. So Box D is at 4th position and box C at 3rd position and Box E is in Pink color.


After combining the both statements we can say that box D is in White color.
Hence, option 5 is correct.
