Bihar Police SI Mains Paper 2 Mock Test - 3 - Bihar Police SI MCQ

The RBI’s “Finances of Panchayati Raj Institutions (PRIs)” report analyzes data from 2.58 lakh Panchayats for 2020-21 to 2022-23, highlighting key findings. Panchayats heavily rely on grants (95%) due to limited own revenue sources like property taxes. Inter-state variations in devolution impact socio-economic outcomes. Inconsistent data poses challenges in assessing fiscal health. PRIs struggle with local tax revenue generation due to a limited tax base, administrative issues, and unclear guidelines. Revenue sources include Central and State government grants, and PRIs have the authority to impose taxes and fees.

Nigeria leads the global fight against meningitis, introducing the groundbreaking Men5CV vaccine, endorsed by WHO, targeting five strains in one shot. This surpasses previous vaccines, vital as bacterial meningitis, prevalent in Africa, poses serious health risks. Africa’s “meningitis belt,” including Nigeria, faces escalating cases, with a 50% rise reported last year by WHO. Nigeria’s pioneering move sets a precedent for broader adoption worldwide, marking a significant stride in public health.

The correct option is A.
After his demise the nobles and specialists at the court chose Muhammad's cousin Firoz ShahTughlaq as the following Sultan, in 1351. He wrote his autobiography called Futuhat-e-firozshahi.

Hence, the applicant meets all the criteria.

The logic follows here is:

In a figure:

Middle number = (Top number × bottom number) - (left number × right number) 

In fig 1:

Middle number = (9 × 10) - (7 × 8)

= 90 - 56

= 34

In fig 2:

Middle number = (12 × 8) - (8 × 7)

= 96 - 56

= 40

Similarly,

In fig 3:

Middle number = (11 × 7) - (4 × 9) 

? = 77 - 36

? = 41

Hence, the correct answer is "41".

Given Statement: P < Q < R < S = T

Conclusion:

I. Q < T → True (As, Q < R < S = T → Thus, it is clear that Q < T. So, the conclusion is true)

II. P > S → False (As, P < Q < R < S → Thus, it is clear that P < S. So, the conclusion is false)

III. R = T → False (As, R < S = T → Thus, it is clear that R < T. So, the conclusion is false)

Hence, the correct answer is "Only conclusion I follows".

From the diagram given below:

The shaded part represents the persons who speak only two languages.

26 + 51 + 17

= 94 

Hence, the correct answer is "94".

The Logic followed here is:

The third number = The First number × (second number ÷ 2)

In Row 1:- 10, 4, 20

The third number = 10 × (4 ÷ 2)

= 10 × 2 = 20

In Row 2:- 15, 8, 60

The third number = 15 × (8 ÷ 2)

= 15 × 4 = 60

Similarly,

In Row 3:- 25, 8, ?

The third number = 25 × (8 ÷ 2)

? = 25 × 4 = 100

Hence, the correct answer is "100".

Additional Information 

The most common pattern asked in exams are based on:

• It could be the sum of two numbers divided by a constant
• It could be the average of numbers.
• It could be in the form of alphabets, where alphabets are increased by constant or increased by the square of numbers or increased by prime numbers.
• It could be the difference of product of two diametrically opposite numbers.
• It could be the difference in the sum of adjacent numbers.
• The difference of the numbers could be in the pattern 13 ± 1, 23 ± 1,  and so on.
• The difference of the numbers could be in the pattern 12 ± 1, 22 ± 1, and so on.
• Numbers could be 12, 22, 32, and so on or 13, 23, 33, and so on.
• The difference could be prime numbers or the difference could be the square of prime numbers.
• The difference could be in the form of N2 ± N or N3 ± N.
• The difference could be in the form of ×N + N or ×2 + 1, ×2 + 2, ×2 + 3, and so on.

• Numbers could be ×1, ×2, ×3, and so on. 

1) DARKEST – SKATEBOARD (Can be formed)

2) ABROAD – SKATEBOARD (Can be formed)

3) STRIKE – SKATEBOARD (Cannot be formed because I is missing)

4) BEAST – SKATEBOARD (Can be formed)

Hence, the correct answer is “STRIKE”.

The logic that follows here is 

1) D is sitting to the immediate left of A.

2) C is sitting to the immediate right of B.

3) B is not sitting adjacent to A.

The final seating arrangement will be

Second to the right of D is 'E'.

Hence, the correct answer is E.

From the final arrangement, we get “Q sits second to the right of the one who sits immediate left of M.
Hence, Option C is correct.
References:
O sits 3^rd to the right of N.
One who sits just behind O is to the immediate right of E.
Inferences:
From the above reference, we get the following cases:

References:
B is neither at any of the extreme ends nor sits exactly behind O.
The number of people sitting between C and E, is the same as the number of people sitting between E and B.
Inferences:
From the above reference, we get the following cases:

References:
D doesn’t sit at any of the extreme ends.
P sits on a seat which is exactly ahead of A.
M is not exactly ahead of E.
Inferences:
From the above reference, we get the following cases:
Case 1: Position of D cannot be fixed, thus this case is eliminated.
​​​​​​​
Case 2: We get the final arrangement as below:

Gauss is the great mathematician who is credited with discovering the total value of the first 100 natural numbers.

You can solve this question using the options. Option (a) fits the given situation best as if we take
the distance as 12 km he would have taken 1 hour to go by car and 4 hours to come back walking
—a total of 5 hours as given in the problem.

3.14 x 10⁶ = 3.14 x 1000000 = 3140000.

If the car does half the journey @ 30 kmph and the other half at 40 kmph it’s average speed can be
estimated using weighted averages.
Since, the distance traveled in each part of the journey is equal, the ratio of time for which the car
would travel would be inverse to the ratio of speeds. Since, the speed ratio is 3:4, the time ratio
for the two halves of the journey would be 4:3. The average speed of the car would be:
(30 × 4 + 40 × 3)/7 = 240/7 kmph.
It is further known that the car traveled for 17.5 hours (which is also equal to 35/2 hours).
Thus, total distance = average speed × total time = (240 × 35)/(2 × 7) = 120 × 5 = 600 km

Let 3889 + 12.952 - x = 3854.002.

Then x = (3889 + 12.952) - 3854.002

= 3901.952 - 3854.002

= 47.95.

Hence, Option A is correct.

Weights → A + B + C + D = 64 × 4 = 256 kg
Weights → A + B = 50 × 2 = 100 kg
Weights → B + C + D = 70 × 3 = 210 kg
Weights → A + B + B + C + D = 100 + 210 = 310 kg
So the answer = 310 – 256 = 54 kg
Hence, Option D is correct.

All even numbers between 1 and 50 = 2 to 48

Hence, Option D is correct.
