JK Police Constable Practice Test - 10 - JK Police Constable MCQ

We follow the given pattern and complete form will be :-
Figure ( d ) will be complete form of given figure .

There are 24 triangles in the given figure. To count the triangles, we can start by counting the individual triangles formed by the lines and then combine them to count the larger triangles. By doing so, we can identify 24 distinct triangles in the figure.

915 - 364 = 551

and 789 - 543 = 246

Similarly, 863 - 241 = 622.

Nitin : 32 31 30 29 28 27 26 25 24 23 22 21 20.....................
Sumit : 1 3 5 7 9 11 13 15 17 19 21 23 25..............................
Clearly, both will never call out the same number.

From the following common explanation, we get that no one sits between Prem and Maaya.
Hence, Option D is correct.
 

Final Arrangement:

Common Explanation:
References:
Ten people were born in ten different years from 1994 to 2003.
Inferences:
So, we need to arrange as follows to accommodate the information stated in the reference:

References:
Ekta was born in a year which is a multiple of 5.
Two people were born between Ekta and Raj.
Sagar was born immediately after Ekta.
Inferences:
From the above references, we get the following cases:

References:
Four people were between Hari and Raj.
Maahi was born immediately before Hari.
Inferences:
From the above references, we get the following cases:

According to the given conditions, Maahi was born immediately before Hari. Thus case 3 is not valid.
References:
Three people were born between Prem and Sagar.
Mahesh was born after Prem.
Inferences:
From the above references, we get the following cases:

According to the given conditions, three people were between Prem and Sagar. Thus case 2 is not valid.
References:
David was born after Tejas but before Maya.
Inferences:
From the above references, we get the final arrangement:

The logic behind the output is as follows:

Step I -

The first and last digit of the first number in Input is added and the sum is written first. The second, third, and fourth digits are written as it is after the sum, and the fifth digit is omitted. The same is continued with other numbers.

Step II -

The first and second digits of the first number in Step I are added and the sum is written first then the third and fourth digits are written as it is after the sum, and then the square of the last digit is written. The same is continued with other numbers.

Step III - 

The first two digits of the first number in Step II are arranged in ascending order then the middle digit is kept as it is and then the the last two digits are arranged in descending order. The same is continued with other numbers.

Step IV - 

The difference between the first two digits of the first number in Step III is written first, then the third and fourth digits are written as it is after the difference and then the double of the last digit is written. The same is continued with other numbers.

Step V - 

The first two digits of the first number in Step IV are added and their square is written as a number. Then the product of the last two digits is written as a separate number. The same is continued with other numbers.

Input:   478667  578688  543867  765879  658574  866734

Step I:  11786    13786    12438    16658    10585    12667

Step II: 27836    47836    34364    76564    15825    36649

Step III: 27863   47863    34364    67564    15852    36694

Step IV:  5866     3866     1368      1568      4854       3698

                  /\          /\             /\          /\            /\             /\ 

Step V: 169 36  121 36     16 48    36 48    144 20     81 72

The second digit from the left of the third number from the left in Step IV is 3 and the fourth digit from the left of the second number from the right end in Step III is 5.

Difference = 5 - 3 = 2 

Hence, the correct answer is 2.

Checking Statement I:

Using the above references, we get the following cases:

Case 1:

Case 2:

 Since there is no clear information about the position of Ramesh so, we cannot say anything about the person who sits on the immediate left of Ramesh.

Clearly, Statement I alone is not sufficient to answer the question.

Statement II:

Using the above references, we get the following cases:

 
Clearly, Statement II alone is not sufficient to answer the question.

Checking both statements I and II:

Using the both statements, we get the following arrangement:

Clearly, Both statement I and II are sufficient to answer the question.

Hence, Option D is correct.

From the common explanation, we can say that H sits 3rd to the left of the one who sits opposite to D.

Hence, Option B is correct.

Common Explanation:

References:

One person sits between A and C, who sits second to the right of H.

G sits opposite to B.

Both G and B do not sit immediate left of H.

Inferences:

From the above reference, we get two different cases:

References:

D sits second to the left of B.

A doesn’t sit beside D.

E doesn’t face C.

Inferences:

From the above reference, case 1 will be eliminated because A doesn’t sit beside of D.

So, the final arrangement:

Given statements:
E = F < G < H       …. (i)
G ≥ I                   …. (ii)
From (i) and (ii), we get
I ≤ G < H                                   …. (iii)
Thus, I < H or H > I is true.
Again, from (i) and (ii), we get
E = F < G ≥ I                              …. (iv)
We can’t compare E and I. Hence, E > I is not true.
Hence, only conclusion I is true.
Hence, option A correct.

The candidate is to be selected. Surya Kumar Yadav has satisfied all the criteria so he will be selected in TELCA softwares.

Draw a table with Student, Collage (Institute) and Subject.
R studies in the same college as P, who studies MBA in college B.
T studies BCA in college A and his brother W studies Aviation Technology in college C.
S studies Journalism in the same college as Q.
Neither R nor Z studies BCA.
The girl who studies BCA does not study in college C.
No girl studies Journalism or MBA.
Two of the seven students study BCA, two study medicine and one each studies Aviation Technology, Journalism and MBA.
Assume + sign is for Boys and - sign is for girls.
Based on the above information, The classification of the group is as follow in the table.

∵ (18 ÷ 9) + 3 x 5 = 45
⇒ (18 + 9) ÷ 3 x 5 = 45
⇒ 27 ÷ 3 x 5 = 45

626-1 = 625 = 25².
962-1 = 961 = 31².
1090-1 = 1089 = 33².
But,
841-1 = 840 (not a perfect square).
Otherwise, 841 is a perfect square of 29, other are not a perfect square.

The exodus can be stopped by providing the people conditions conducive to living. So, both the courses follow.

Both the statement I and II are effects of independent causes. Because spreading malaria or to be suffering from malaria may be due to mosquitoes or dirtiness. But the decision of Private practitioners to close the clinics may be due to other cause.

Opening up of new industries is advantageous in opening more employment avenues, and disadvantageous in that it adds to the pollution. So, either of the arguments holds strong.

That someone has earned a lot is no reason to share the profit margin with the customers. So, I is not implicit. Clearly, the offers have been announced to attract more customers and boost up the sale. So, II is implicit.

The statement mentions that a new study has found that people who exercise regularly have a lower risk of developing heart disease. From this, it can be inferred that regular exercise can help reduce the risk of developing heart disease. This is a logical inference from the given statement. However, it is not mentioned that people who don’t exercise regularly are guaranteed to develop heart disease, making option I incorrect. Option II is also incorrect as exercise is not the only factor that affects the risk of developing heart disease.

From the common explanation, we can see that Q is in north east direction with respect to I.
Hence, Option C is correct.
Common Explanation:
Reference:
Z is 25 cm to the north of A.
Y is 65 cm to the east of A.
H is 7 cm south of Y.
I is 65 cm to the west of H.
J is 10 cm to the west of Z.
Y is 25 cm to the south of Q.
Inference:
From the above statement, we get the final figure as below:

The All four part of the the figure is identical. So after folding the 2 times of the figure, it will become figure like option C.

As per the given above question , we can say that
Elephant and Wolves bear no relationship to each other while both are animals.
Hence , option A is correct answer .

In the given figure, we can identify six triangles. There are three small triangles formed by the intersection of the three vertical lines and the horizontal line at the bottom. Additionally, there are two larger triangles formed by the intersection of the two diagonal lines and the horizontal line at the top. Lastly, there is one triangle formed by the intersection of the two diagonal lines and the vertical line in the middle. Therefore, the correct answer is 6.

(10 + 20 + 30) × 2 = 120; (15 + 25 + 35) × 2 = 150.
So, missing number = (10 + 15 + 25) × 2 = 100.

Subtract 2 from odd digits in given number and add 3 in even digits.

So, in new number there are two digits of five and two digits of seven.

From the common explanation, we can conclude that 3 persons are elder than Q.
Hence, option A is correct.
Final Arrangement:

Common Explanation:
References:
Nine people J, K, L, M, N, O, P, Q and R were born on the 13th of nine different months of the year 2000 but not necessarily in the same order.
No one was born after October and none of them was born in January.
Only one person was born in one month.
For all calculations of ages use 2022 as the current year.

Inferences:
From the above references, we can conclude the following:

References:
Three persons were born between O and K, where both were born in a month having 31 days.
The number of persons born before N is the same as the number of persons born after N.
Inferences:
From the above references, we can conclude the following cases:

References:
The number of persons born between O and N is the same as the number of persons born between N and M.
J was born in the month of having 30 days, but not in September.
Inferences:

References:
The number of persons born after K is the same as the number of persons born before Q.
L was born in the month having days less than 31.
Inferences:

References:
P was born before R.
The number of persons born between P and Q is the same as the number of persons born between Q and L.
Inferences:
From the above references, we can eliminate case 2.
Hence, the final arrangement is as follows:

In the first step, the largest number comes to the first position and the remaining line shift rightward. In the next step the word that comes first in the alphabetical order goes on to occupy the second position pushing the rest of the shift rightward. This goes alternately till all the number are arranged in a descending order and all the words in alphabetical at alternate positions.
Step II : 75 down 16 24 farm eager 62 sky
Step III : 75 down 62 16 24 farm eager sky
Step IV : 75 down 62 eager 16 24 farm sky
Step V : 75 down 62 eager 24 16 farm sky
Step VI : 75 down 62 eager 24 farm 16 sky
Hence 6 - 2 = 4 more steps will be required.

From Statement 1:

No one has exam after S.

Three people has exam between S and R.

N has exam before R.

M has exam after Thursday.

W has exam before B.

From, this statement, we get:

 So, from this statement, N has exam immediately after B.

From Statement 2:

Two people have exam before R, who has exam immediately after S.

B has exam after R but not on Saturday.

N has exam immediately after H.

From this statement, M has exam immediately after B.

So, either statement 1 or statement 2 alone is sufficient to answer the question.

Hence option C is correct.

From the final arrangement, we get, R doesn’t belong to that group as except for R, all the others are facing outside.
Hence, Option D is correct.
References:
Q sits second to the right of P.
Inferences:
From the above reference, we get two different cases:
In case 1, P sits at the corner or in the middle of the side of the table.

References:
R is not an immediate neighbor of P.
R faces inside.
R sits third to the left of W.
Inferences:
From the above references, we get different cases for R, in case 1(a) in which R faces P and in case 1(b) R faces Q.

References:
T sits third to the left of U.
V sits second to the left of U.
Inferences:
So, from this case 1(b) and case 2 will be eliminated as there is no possible place for V in these cases after placing U and T. Hence, we get our final arrangement in which S sits on the immediate left of P and V sits on the immediate right of R.
Final arrangement:
