MP Police Constable : (7 Nov 2025, Shift 1) Memory-Based Paper (Previous Year Paper)

Karim ranks 15^th from the top in a class of 49 students.

Karim’s rank from the bottom = 49 – 15 + 1

= 50 – 15

= 35

So, his rank from the bottom is 35^th.

Hence, ‘35’ is the correct answer.

Given:

R = radius of the top circular face = 35 cm

r = radius of the bottom circular face = 28 cm

h = height of the bucket

Formula used:

Volume of frustum = \(\dfrac{1}{3} \pi h (R^2 + r^2 + Rr)\)

Volume of the frustum = 187.88 litres = 187.88 × 1000 cm3 = 187880 cm3

Calculations:

Volume of the frustum = 187880 cm3

\(\dfrac{1}{3} \pi h (R^2 + r^2 + Rr) = 187880\)

\(\dfrac{1}{3} \times \dfrac{22}{7} \times h \times (35^2 + 28^2 + 35 \times 28) = 187880\)

\(\dfrac{22}{21} \times h \times (1225 + 784 + 980) = 187880\)

\(\dfrac{22}{21} \times h \times 2989 = 187880\)

⇒ \(h = \dfrac{187880 \times 21}{22 \times 2989}\)

⇒ \(h = \dfrac{3945480}{65758}\)

⇒ h = 60 cm

∴ The correct answer is option 3.

The logic followed here is:

Hence, 'FHC' is the correct answer.

The correct answer is option 3.

The correct option is a live wire.

Key Points

• The fuse must be connected to the circuit's live wire.
• The appliance will still be linked to high potential through live wire even though the fuse will melt if it is attached to a neutral wire when there is an excessive current flow.
• As a result, the appliance shocks everyone who touches it.

Additional Information

Live wire:

• An electrical wire that allows current to flow through it.
• Mostly it is red in color.

Neutral wire:

• The neutral wire's job is to finish the circuit by providing a route back to the electrical panel.
• Where it is joined and bonded to the earth's ground.
• Mostly it is black in color.

Earth wire:

• We are shielded from electric shocks by the ground wire that earths the metallic body of high-power electrical equipment.
• It prevents live wire overloading and permits no electric charge leakage through the body of metallic appliances that may be readily conducted to the ground.
• The green color is used for this wire.

The pattern followed is,

All follow the same pattern, except ‘FJN’.

Hence, “FJN” is the odd – cluster.

Given:

55% students passed in English, 35% students passed in Mathematics and 20% students passed in both the subjects.

Calculation:

55% students passed in English, 35% students passed in Mathematics and 20% students passed in both the subjects.

Students passed = (55 + 35 - 20)% = 70%

Students failed = (100 – 70)% = 30%

According to question,

30% = 1200

⇒ 100% = (1200/30) × 100 = 4000

∴ 4000 students appeared in the examination.

The combinations are:

Rahul + Kusum = Hindi + Maths------ (i )

Sameer + Rahul = Hindi + Biology-------(ii)

Gita + Kusum = Marathi + Maths-------(iii)

Sameer + Gita + Mihir = History + Biology-------(iv)

There can be two possible combinations for Marathi and Biology:

Using (ii) and (iii)

Sameer + Rahul = Hindi + Biology-------(ii)

Gita + Kusum = Marathi + Maths-------(iii)

But here no one is common so we cannot determine that person who is good in both Marathi and Biology.

Using (iii) and (iv)

Gita + Kusum = Marathi + Maths-------(iii)

Sameer + Gita + Mihir = History + Biology-------(iv)

Here Gita is common, so Gita is good in both Biology and Marathi.

Given:

The radius of 3 small spherical ball = 6 cm, 8 cm and 10 cm

Concept used:

The volume of 3 spherical melted balls = Volume of 1 big spherical ball

Formula used:

The volume of sphere = (4/3) × π × r3

where,

r →  Radius of the sphere

The volume of big sphere = (The volume of the first sphere + The volume of the second sphere + The volume of the third sphere)

Calculations:

According to the question, we have

The volume of sphere = (4/3) × π × r3

The volume of the big ball = {(4/3) × π × (6)³} +  {(4/3) × π × (8)³} + {(4/3) × π × (10)³}

⇒ (4/3) × π × r3 = (4/3) × π × (216 + 512 + 1000)

⇒ r³ = 1728

⇒ r = 12

Now,

The total surface area of the big spherical ball = 4πr²

⇒ 4π × (12)²

⇒ 4π × 144

⇒ 576π

∴ The total surface area of the big spherical ball is 576π cm².

The correct answer is Article 315.

No of days from 3^rd February 2015 to 6^th June 2015  = 25 + 31 + 30 + 31 + 6 = 123  as 2015 is a non-leap year.

Since, it was Tuesday on 3^rd February 2015, every 7^th day from 3^rd February will be a Tuesday.

Thus, no. of odd days = 123/7 = 4

Now,  3^rd February 2015 (Tuesday) + 4 odd days = 6^th June 2015 (Saturday)

6^th June 2015 will be Saturday.

Hence, "option 4" is the correct answer.

Let the outer and inner radius of the pipe be ‘R’ and ‘r’ cm

Since difference of outside and inside surface areas of the pipe is 132 cm²

⇒ 2πRh - 2πrh = 132

⇒ 2 × 22/7 × 21 × [R - r] = 132

⇒ [R - r] = 1 ----(1)

And

Since the volume of the pipe is 264 cm³;

⇒ π(R² - r²) × h = 264

⇒ 22/7 × (R² - r²) × 21 = 264

⇒ (R² - r²) = 4

⇒ (R - r) (R + r) = 4

Putting [R - r] = 1

⇒ (R + r) = 4 ----(2)

From equation 1 and 2

⇒ R = 2.5 cm and r = 1.5 cm

∴ Inner radii of the pipe = 1.5 cm

Karim's rank from the bottom = Total students - Rank from the top + 1

Karim's rank from the bottom = 49 - 16 + 1 = 34.

Hence, the correct answer is "34".

Given:

if x2 − 2x + 1 is a factor of 2x4 + x3 − 14x2 + 5k + 6.

Calculation:

if x2 − 2x + 1 is a factor of 2x4 + x3 − 14x2 + 5k + 6, then

Factors of x2 − 2x + 1 = (x - 1)² = (x - 1) (x - 1) 

∴ x = 1 is the factor of 2x4 + x3 − 14x2 + 5k + 6.

Put x = 1 in this polynomial,

⇒ 2(1)⁴ + (1)³ - 14(1)² + 5k + 6 = 0

⇒ 2 + 1 - 14 + 5k + 6 = 0

⇒ 5k = 5 

∴ k = 1

Let radius of cylinder be r and radius of sphere be R

Volume of a right circular cylinder = πr²h

Volume of a sphere = (4/3)πR³

Given,

R = 2r

Ratio of the volumes of a right circular cylinder and a sphere is 3 : 2

\(\Rightarrow \;\frac{{\pi {r^2}h}}{{\frac{4}{3}\pi {R^3}}}\; = \;\frac{3}{2}\)

⇒ h = 16r

Curved Surface area of a right circular cylinder = 2πrh

Surface area of the sphere = 4πR²

∴ Ratio of the surface areas of the cylinder and the sphere \(= \;\frac{{2\pi rh}}{{4\pi {R^2}}}\; = \;\frac{{32{r^2}}}{{4 \times 4{r^2}}}\; = \;2\;:\;1\)

Given series is SORROW ∶ ROWROS ∶∶ DEGREE ∶ ?

As SORROW ∶ ROWROS

Similarly, DEGREE ∶ ?

Hence, the correct answer is "DEGREE ∶ REEGED".

Shortcut Trick

Identify the squares: a², 4b² = (2b)², and 9c² = (3c)².

Check signs of cross-products: −4ab and −6ca are negative, while 12bc is positive.

Since 12bc is positive, b and c must have the same sign (both − or both +).

Since −4ab and −6ca are negative, a must have the opposite sign of b and c.

Testing signs: (a − 2b − 3c)² gives −4ab, +12bc, and −6ca.

∴ The correct answer is (a − 2b − 3c)².

Alternate Method

Given: The expression is a² + 4b² + 9c² − 4ab + 12bc − 6ca.

Formula Used: The standard Trinomial Square Identity: (x + y + z)² = x² + y² + z² + 2xy + 2yz + 2zx.

Comparing the given expression with the identity:

⇒ x² = a² → x = a

⇒ y² = 4b² → y = ±2b

⇒ z² = 9c² → z = ±3c

⇒ 2xy = −4ab ⇒ 2(a)(y) = −4ab ⇒ y = −2b

⇒ 2zx = −6ca ⇒ 2(z)(a) = −6ca ⇒ z = −3c

⇒ 2yz = 2(−2b)(−3c) = 12bc (Matches the given term)

⇒ Therefore, the factorized form is (x + y + z)² = (a − 2b − 3c)².

∴ The correct answer is (a − 2b − 3c)².

Additional Information

Trinomial Expansion Rule

The expansion of (a + b + c)² always results in 3 squared terms (always positive) and 3 cross-products. The signs of the cross-products depend entirely on the relative signs of a, b, and c.

Perfect Square Recognition

If an algebraic expression has the form x² + y² + z² + 2xy + 2yz + 2zx, it is a perfect square of the trinomial (x + y + z).

Sign Analysis

In (a − b − c)², only the terms involving 'a' multiplied by others (ab and ac) will be negative, while the product of two negatives (bc) becomes positive.

Given:- \(x-\frac{1}{x}=5\)

To find:- The value of \(x^{3}-\frac{1}{x^{3}}\)

Formula used:- a³ - b³ = (a - b)(a² + b² + ab) and (a - b)² = a² + b² - 2ab

Calculation:- As it is given, \(x-\frac{1}{x}=5\)

On squaring both sides,

⇒ \(\left(x-\frac{1}{x}\right)^2=5^2\)

⇒ \(x^2+\frac{1}{x^2} -2= 25\)

⇒ \(x^2+\frac{1}{x^2} = 27\)

We have to find the value of \(x^{3}-\frac{1}{x^{3}}\),

By using the formula a3 - b3 = (a - b)(a2 + b2 + ab), we can write the equation as-

⇒ \(x^{3}-\frac{1}{x^{3}} = (x-\frac{1}{x})\left(x^2+\frac{1}{x^2}+1\right)\)

Now, by substituting the value,  \(x-\frac{1}{x}=5\) and \(x^2+\frac{1}{x^2} = 27\),

⇒ \(x^{3}-\frac{1}{x^{3}} = 5× \left(27+1\right)\)

⇒ \(x^{3}-\frac{1}{x^{3}} = 5× 28 = 140\)

.·.The value of expression \(x^{3}-\frac{1}{x^{3}}\) is 140

Shortcut TrickIf x - 1/x = a then \(x^{3}-\frac{1}{x^{3}}\) = a³ + 3a

x - 1/x = 5 ⇒ \(x^{3}-\frac{1}{x^{3}}\) = 5³ + 5 × 3 = 140

The logic is;

37: 259 → 37 × 7 = 259

Similarly,

17: ‘?’ → 17 × 7 = 119

Hence, ‘119’ is related to 17.

Given:

The numbers are 12, 15, 11, 13, 17, 11, 13, 12, 13

Concept used:

The following steps are helpful while applying the median formula for ungrouped data.

• Step 1: Arrange the data in ascending or descending order.
• Step 2: Secondly, count the total number of observations 'n'.
• Step 3: Check if the number of observations 'n' is even or odd.

When n is odd

Median = [(n + 1)/2]th term

When n is even

Median = [(n/2)th term + ((n/2) + 1)th term]/2

Mean = Sum of numbers/total numbers

Calculation:

Total of the numbers = 12 + 15 + 11 + 13 + 17 + 11 + 13 + 12 + 13

⇒ 117

So, mean = 117/9

⇒ 13

Now,

The numbers in ascending order = 11, 11, 12, 12, 13, 13, 13, 15, 17

Now, the median is (9 + 1)/2 = 5^th term i.e 13

So, sum of mean and median = 13 + 13

⇒ 26

∴ The required answer is 26.

∴ Option 1 is the correct answer.

The correct answer is Jute.

• Globalization is a huge term. It has come to be used in every industry and in every geographical location.
• It has influenced trade and commerce of all types.
• It has brought countries together.
• There were no way warring countries could be united except by trade.
• Globalization has had many advantages. But it also has this drawback.
• It has led to the emergence of sweatshops. A new kind of exploitation has been given birth to.
• Corporate giants are cashing in on the poverty of the developing countries and making the already developed countries poorer.
• Textile manufacturers should outsource their work to other countries, but not after denying even the basic wages to the overseas employees.
• Agro-based traditional industries play a vital role in industrialization in an underdeveloped economy.
• The Indian jute industry has been globally significant since colonial times and enjoyed a "major industry" status.
• Under globalization, it is found that the key structural ratios like labour productivity, capital intensity, and total factor productivity have been increasing. Hence, Option 3 is correct.
• But the falling trend of capital productivity with low growth of capital-output ratio signifies the general deterioration of the quality of investment and its improper utilization over time.
• The lower ratio of value-added to output also indicates the use of cost-ineffective technology by the industry.
• At the organizational level, this low value-added to output also signifies smaller factory sizes and increasing horizontal integration within the sector.

1) P lives on third floor which is immediately above Q.

2) T lives immediately above P and immediately below R.

3) U lives on the floor immediately above V & S does not live on any floor immediately above U or above R.

So, S lives on the first flour.

Hence, the correct answer is 'S'.

Given:

Amount (A) = ₹19467.20

Rate (r) = 15% per annum

Time (t) = 3 years

Formula used:

A = P(1 + r/100)^t

Where, A = Amount, P = Principal, r = Rate, t = Time

Calculation:

19467.20 = P(1 + 15/100)³

⇒ 19467.20 = P(1.15)³

⇒ 19467.20 = P × 1.520875

⇒ P = 19467.20 / 1.520875

⇒ P = 12800

∴ The correct answer is option (1).

Similarly,

Hence, “2-19-17-18” is the correct answer.

Given:

Three numbers are in the ratio 19 : 21 : 23.

The difference between thrice the third number and the sum of the first and second numbers is 841.

Calculations:

Let the number be x as, 19x, 21x, 23x

According to the question,

Difference between thrice the third number and the sum of the first and second numbers.

3 × 23x - (19x + 21x) = 841

⇒ 69x - 40x = 841

⇒ 29x = 841

⇒ x = \(\dfrac{841}{29}\) = 29

Now, The difference between the first and third numbers = 23x - 19x

⇒ x(23 - 19)

⇒ 29 × (23 - 19)

⇒ 29 × 4 = 116 

∴ The answer is 116

Age difference remains constant at 8 years.

4 years ago, Ratio A : B = 1 : 2. Difference = 2 − 1 = 1 unit.

1 unit = 8 years → B's age 4 years ago = 2 × 8 = 16 years.

Present age of B = 16 + 4 = 20 years.

∴ The correct answer is 20 years.

Alternate Method

Given: Present age difference = 8 years. Ratio 4 years ago = 1 : 2.

Formula: Age = Ratio unit × Value + Time elapsed.

⇒ Let ages 4 years ago be x and 2x.

⇒ Difference = 2x − x = 8

⇒ x = 8

⇒ B's age 4 years ago = 2 × 8 = 16 years.

⇒ B's Present age = 16 + 4 = 20 years.

∴ The correct answer is 20 years.

Additional Information

Given:

Reena sells an article at 12% below its cost price. Had she sold it for ₹540 more, she would have gained 15%.

Formula used:

Selling Price (SP) = Cost Price (CP) + Profit

Profit% = \(\dfrac{Profit}{CP} \times 100\)

Calculations:

Let CP = x

SP at 12% loss = x - 0.12x = 0.88x

SP at 15% profit = x + 0.15x = 1.15x

Given, 1.15x = 0.88x + 540

⇒ 0.27x = 540

⇒ x = 2000

To gain 20%, SP should be: 2000 + 0.20 × 2000

⇒ SP = 2000 + 400 = 2400

∴ The correct answer is option (3).

Curved Surface Area (CSA) of a frustum can be calculated using the perimeters (circumferences) of its bases.

CSA = (Sum of Perimeters ÷ 2) × Slant Height

⇒ CSA = [(20 + 12) ÷ 2] × 8

⇒ CSA = (32 ÷ 2) × 8 = 16 × 8 = 128 cm²

∴ The correct answer is 128 cm².

Alternate Method

Given:

Slant height (l) = 8 cm

Perimeter of larger base (P₁) = 20 cm ⇒ 2πR = 20

Perimeter of smaller base (P₂) = 12 cm ⇒ 2πr = 12

Formula Used:

Curved Surface Area (CSA) of frustum = π(R + r)l

Calculations:

⇒ 2πR + 2πr = 20 + 12

⇒ 2π(R + r) = 32

⇒ π(R + r) = 16

⇒ CSA = π(R + r) × l

⇒ CSA = 16 × 8

⇒ CSA = 128 cm²

∴ The correct answer is 128 cm².

Additional Information

Total Surface Area of Frustum

TSA = π(R + r)l + πR² + πr². It includes the CSA and the area of both circular bases.

The correct answer is Decibel.

Key Points

• Decibel
• The sound is all around us and can be measured to protect and inform us, as some sounds are not safe.
• In fact, loud noise can actually damage our hearing. So, the intensity of a sound is measured using decibel.
• Decibel is the unit of sound. Its symbol is dB. Hence, Option 1 is correct.
• The decibel (dB) is a unit used to express the ratio of two values of a physical quantity, often power or intensity.
• One decibel is one-tenth of one bel, a unit name named in honour of Alexander Graham Bell. This unit ‘bel‘ is seldom used.
• The human ear has the ability to handle an immense range of different sound levels. Therefore, to express sound levels meaningfully in more flexible numbers, a logarithmic scale is used, rather than a linear one. This scale is called the decibel scale or dB scale.
• On the decibel scale, 0 dB is the smallest audible sound.
• A sound 10 times more powerful is 10 dB.
• A sound 100 times more powerful than near total silence is 20 dB.
• A sound 1,000 times more powerful than near total silence is 30 dB.

Additional Information

• A dioptre or diopter is a unit of measurement of the optical power of a lens or curved mirror, which is equal to the reciprocal of the focal length measured in meters.
• It is thus a unit of reciprocal length. For example, a 3-dioptre lens brings parallel rays of light to focus at 1⁄3 meter.
• Parsec, unit for expressing distances to stars and galaxies, used by professional astronomers.
• It represents the distance at which the radius of Earth’s orbit subtends an angle of one second of arc.
• Thus, a star at a distance of one parsec would have a parallax of one second, and the distance of an object in parsecs is the reciprocal of its parallax in seconds of arc.

GIven:

In the 12^th innings, Sachin Tendulkar scores = 120 runs

Formula used:

Average = sum of all numbers/total number

Calculation:

Let Sachin Tendulkar, average scores in 11^th innings be x

Total runs in 11^th innings = 11 × x

⇒ 11x

After increasing the average by 5 runs, new average = x + 5

⇒ (Total runs in 11^th innings + runs in 12^th innings)/12 = x + 5

⇒ (11x + 120)/12 = x + 5

⇒ (11x + 120) = (x + 5) × 12

⇒ 11x + 120 = 12x + 60

⇒ 12x – 11x = 120 – 60

⇒ x = 60

New average = 60 + 5

⇒ 65

∴ The new average is 65.

Shortcut Trick

Actually after scoring 120 runs in 12^th innings the average increased by 5 runs.

then total increased runs = 12 × 5 = 60 runs

Now previous average should be 120 - 60

⇒ 60 runs

New average = 60 + increased average 

⇒ New average = 60 + 5

⇒ 65 runs

∴ The new average is 65.

The correct answer is Radon.

1. Radioactivity is a nuclear phenomenon in which an unstable nucleus undergoes decay and is referred to as radioactive decay.
2. Three types of radioactive decay occur in nature :

(i) α-decay (ii) β-decay (iii) γ-decay 3. Noble Gases

1. There are six elements in Group 18 of the Periodic Table - Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr) , Xenon (Xe) and Radon (Rn) which were earlier termed as inert gases or rare gases.
2. Both of these terms are now no longer used as they are not so rare and not completely inactive. They do show some chemical reactivity in the form of some xenon and krypton compounds and hence are termed as noble gases.
3. Occurrence
4. All the noble gases except Radon occur in the atmosphere. Xenon and radon are the rarest elements of the group.
5. Radon is a radioactive element. Radon (²²²Rn) is a decay product of Radium (²²⁶Ra) and is obtained by pumping off the gas from radium chloride solutions.
6. They are the minor constituent of the air, the atmospheric abundance being ~ 1% by volume of which argon is the major constituent. Ne, Ar, Xe and Kr are obtained by fractional distillation of liquid air.
7. Helium and sometimes neon is found in minerals of radioactive origin e.g., pitchblende, monazite, cleveite. The main commercial source of helium is natural gas to an extent of 2-7%.
8. They have closed valence shell electronic configuration due to which they have the least tendency to react.
9. The best-characterised compounds are those of xenon with fluorine and oxygen only under certain conditions and only with highly electronegative fluorine and oxygen.
10. Uses: These gases have several uses. Argon is used to provide an inert atmosphere, helium is used in filling balloons for meteorological observations, neon is used in discharge tubes and fluorescent bulbs.

Hour hand covers 3600 in 12 hours

Angular distance covered in 1 hour = 360/12 = 300

Angular distance covered in 60 minutes = 300

Angular distance covered in 1 minutes = 1/20

CALCULATION:

Minute hand covers 360 in 60 minutes

60 minutes = 3600

1 minute =360/60

1 minute = 60

Here minute = 45

Angle covered by minute hand = 45 × 6 = 2700

Angle covered by hour hand = 6 × 30 + 45 × ½ = 180 + 22.5 = 202.50

Angle between hour and minute hands = 270 – 202.5 = 67.50

Hence, angle between hour and minute hands is 67.50

Formula to calculate angle (N) between Minute hand and hour hand is:

 \(N= 11/2 ×M-30 ×H\)

\(N= 11/2 ×45-30×6\)

\(N = 495/2-180\)

N = 67.5^o.

hence, the correct answer is  67.5o.
