Explanation:- Light is an electromagnetic wave and hence it has a speed which is much higher than the speed of sound. So during lightning, the light reaches earlier than the sound. So the assertion is incorrect but the reason is correct.

The flash of lightning during a thunderstorm is a light ray which is an electromagnetic wave. The speed of light in vaccum is given by 3 x 10⁸m/s which is much more than the speed of sound.

So when lightning strikes then the flash of light reaches us much faster than the sound does.

Hence, the correct answer is A is false but R is true.

Option 3 : Arunachal Pradesh

Shortcut Trick

Pratham's Cost Price = Anya's Cost Price ÷ 1.20 ⇒ 2244 ÷ 1.2 = 1870

Marked Price after first 15% discount = 2500 × 0.85 = 2125

Second discount amount = 2125 − 1870 = 255

Value of D = (255 ÷ 2125) × 100 = 12

∴ The correct answer is 12.

Alternate Method

Given:

Marked Price (MP) = Rs. 2500

First discount = 15%

Second discount = D%

Pratham's Profit = 20%

Pratham's Selling Price (Anya's CP) = Rs. 2244

Formula Used:

Selling Price = Cost Price × (100 + P%) ÷ 100

Selling Price = MP × (100 − D₁%) ÷ 100 × (100 − D₂%) ÷ 100

Calculations:

⇒ Pratham's CP × (100 + 20) ÷ 100 = 2244

⇒ Pratham's CP × 1.20 = 2244

⇒ Pratham's CP = 2244 ÷ 1.20 = 1870

⇒ Trader's Selling Price = Pratham's CP = 1870

⇒ MP × (100 − 15) ÷ 100 × (100 − D) ÷ 100 = 1870

⇒ 2500 × 0.85 × (100 − D) ÷ 100 = 1870

⇒ 2125 × (100 − D) ÷ 100 = 1870

⇒ 100 − D = (1870 × 100) ÷ 2125

⇒ 100 − D = 187000 ÷ 2125

⇒ 100 − D = 88

⇒ D = 100 − 88 = 12

∴ The correct answer is 12.

Additional Information

Successive Discounts

When two successive discounts of a% and b% are given, the equivalent single discount is (a + b − a × b ÷ 100)%.

Marked Price & Selling Price

Discounts are always calculated on the Marked Price (MP). Selling Price (SP) = MP × (100 − Discount%) ÷ 100.

Cost Price & Profit

Profit percentage is calculated exclusively on the Cost Price (CP). Selling Price (SP) = CP × (100 + Profit%) ÷ 100.

Given:

In the first alloy,

Copper = 80%

Magnesium = 5%

Zinc = 15%

In the mixture,

Copper = 75%

Magnesium = 20%

Zinc = 5%

Calculation:

In the first alloy, zinc is 15%

In the second alloy, zinc is 0%

In the mixture, zinc is 5%

By the rule of the allegation, we get

Therefore, the first alloy and second alloy are mixed in the ratio of 1 : 2.

In the first alloy, magnesium is 5%

In the second alloy, suppose magnesium is x%

In the mixture, magnesium is 20%

By the rule of the allegation, we get

According to the question,

⇒ (x - 20) : 15 = 1 : 2

⇒ 2x - 40 = 15

⇒ 2x = 55

⇒ x = 27.5%

∴ The Magnesium in second alloy is 27.5%.

Shortcut Trick

Since the speeds are constant, Time is directly proportional to the Total Distance (sum of lengths).

Initial total length = 160 + 180 = 340 m → 15 sec

New total length = 160 + (180 × 1.5) = 160 + 270 = 430 m

New Time = (15 ÷ 340) × 430 = (15 × 43) ÷ 34 ≈ 18.97 sec

Rounding off, we get 19 sec.

∴ The correct answer is 19 sec.

Alternate Method

Given:

Length of Train 1 (L₁) = 160 m

Length of Train 2 (L₂) = 180 m

Crossing time (T₁) = 15 sec

Formula Used:

Relative Speed = Total Distance ÷ Time = (L₁ + L₂) ÷ T

Calculations:

⇒ Initial Relative Speed = (160 + 180) ÷ 15 = 340 ÷ 15 m/s

⇒ New length of Train 2 = 180 + (50% of 180) = 180 + 90 = 270 m

⇒ New Total Distance = 160 + 270 = 430 m

⇒ New Time taken = New Distance ÷ Relative Speed

⇒ New Time = 430 ÷ (340 ÷ 15) = (430 × 15) ÷ 340

⇒ New Time = (43 × 15) ÷ 34 = 645 ÷ 34 ≈ 18.97 sec

∴ The correct answer is 19 sec.

Additional Information

Relative Speed in Opposite Direction

When two objects move in opposite directions, their relative speed is the sum of their individual speeds: V_rel = V₁ + V₂.

Relative Speed in Same Direction

When two objects move in the same direction, their relative speed is the difference of their speeds: V_rel = |V₁ − V₂|.

Crossing Distance Rule

When a train crosses another train or a platform, the total distance covered is the sum of their lengths (L₁ + L₂).

Unit Conversion

To convert speed from km/hr to m/s, multiply by 5/18. To convert m/s to km/hr, multiply by 18/5.

Given:

The difference between the marked price and the cost price is 50% of the selling price.

The discount percentage is 20%.

Concept:

$Selling \ Price=Marked \ Price (\frac{100-Discount \%}{100})$

Solution:

The selling price after 20% discount will be,

$Selling \ Price=Marked \ Price (\frac{100-20 \%}{100}) \ Selling \ Price=Marked \ Price (\frac{80}{100}) \ Selling \ Price=Marked \ Price(0.8)$

According to the question,

Marked Price - Cost Price = 50% of Selling Price

Marked Price - Cost Price = 50% of [Marked Price (0.8)]

$Marked \ Price - Cost \ Price = \frac{50}{100}\times(0.8Marked \ Price))\ Marked \ Price - Cost \ Price = 0.4[Marked \ Price]\ 0.6 [Marked \ Price]=Cost \ Price\ \frac{Marked \ Price}{Cost \ Price}=\frac{1}{0.6}=\frac{5}{3}$

Marked Price : Cost Price = 5 : 3

Given:

Five men and six women or four men and eight women can complete a piece of work.

Concept:

Work done by five men and six women =  Work done by four men and eight women

Solution:

According to the question,

Five men & six women or four men & eight women can complete a piece of work.

5 M + 6 W = 4 M + 8 W

5 M - 4 M = 8 W - 6 W

1 M = 2 W

M : W = 2 : 1

Given:

A train takes 2 minutes to cross a stationary pole.

A platform whose length is three times that of the train.

Concept:

$Speed = \frac{Distance}{Time}$

Solution:

Let the length of the train be A meters

Time is taken by the train to cross a stationary pole = 2 minutes = 120 seconds

Speed of train $=\frac{\text{Length of the train}}{Time} \ m/sec$

Speed of train $=\frac{A}{120} \ m/sec$

According to the question, the length of the train is three times that of the train.

So, the length of the platform = 3A meters

Also,

Speed of train $=\frac{\text{Length of the train + Length of the bridge}}{Time}$

Substituting the value in the above expression we will get,

$\frac{A}{120} = \frac{A+3A}{T} \ T=\frac{4A\times 120}{A} \ T=480 \ sec$

Given:

The greatest six-digit number when divided by 15, 18, 20, 27 and 30 leaves the remainder 9, 12, 14, 21 and 24.

Concept:

A least common multiple of the divisor.

Difference of the divisor and their remainder individually.

Required Number = LCM( x ) - Difference, where x is a positive number.

Solution:

LCM of 15, 18, 20, 27, and 30 = 540

Difference of the given divisor with their respective remainder,

15 - 9 = 6

18 - 12 = 6

20 - 14 = 6

27 - 21 = 6

30 - 24 = 6 

The required number let's say A we will be,

A = 540 (x) - 6

The greatest 6-digit number is 999999

Dividing 999999 by 540 to get the approx value of x

999999 / 540 ≈ 1851

A = (540 X 1851) - 6

A = 999540 - 6

A = 999534

Given:

The table shows the number of teachers male and female in various universities and the percentage of PhDs in them.

Concept:

$Average= \frac{Sum \ of \ the \ observation }{Number \ of \ the \ observation}$

Solution:

Sum of the observation = 180 + 250 + 200 + 350 + 300 = 1280

Number of the observation = 5

$Average = \frac{1280}{5}=256$

Given:

A sum of Rs. 3249 is received at compound interest at the rate of 14% per annum for 2 years.

Formula used:

$A=P[1+ \frac {r}{100}]^n$

Where, A = Amount, P = Principle, r = rate, n = time

Solution:

$A=P[1+ \frac {r}{100}]^n$

⇒ 3249 = P (1 + 14/100)²

⇒ 3249 = P (1+ 7/50)²

⇒ 3249 = P (57/50)²

⇒ P = 3249 × 50/57 × 50/57

⇒ P = 50 × 50

⇒ P = Rs. 2500

∴ The correct answer is option (2).

Given:

In 2010 A family of 5  people has average age = 50 years

One eldest person died in = 2015

And a new baby was born in = 2015

In 2019 average age of family = 45 years

Calculation:

If no member had died and no new member had joined the family, the average age in 2019 = 50 + 9 = 59 years. But it is 45 years.

The average age decreased by 14 years (59 - 45)

So, the decrease in the total age of family  = 5× 14 = 70 years

The age of baby in 2019 = 4 years

So, the age of eldest man had been alive is 70 + 4 = 74 years

 ∴ If the eldest person was alive in 2019 his age would be 74 years.

Alternate Method

In 2019 the age of the baby = 4 year

Average age of the family in 2019 = 45 years

So, total age of the family in 2019 = 45× 5 = 225 years

So, total age of remaining 4 members in 2019 = 225 - 4 = 221 years

or, total age of the remaining 4 members in 2010 = 221 - (9× 4) = 185 years

Total age of the family of 5 member in 2010 = 50 × 5 = 250 years

So, the age of the eldest member of the family in 2010 = (250-185)years = 65 years

So, if the eldest person was alive in 2019 his age would be (65+9) = 74 years

 ∴ If the eldest person was alive in 2019 his age would be 74 years.

Given:

The HCF and LCM of the two numbers are 40 and 840 respectively.

One of the numbers is 280.

Concept:

For any two numbers A and B,

HCF X LCM = Product of the numbers (A X B)

Solution:

HCF = 40

LCM = 840

A = 280

B = ?

40 X 840 = 280 X B

⇒ 33600 = 280 X B

⇒ B = 33600 / 280

⇒ B = 120

Given:

A and B invest in the ratio of 3 ∶ 7 and C invests Rs 8,000, which is the same amount as the difference between the investments of A and B.

Concept:

Investment of A - Investment of B = Investment of C

Solution:

Let the amount invested by A is Rs. A and amount invested by B is Rs. B

A : B = 3 : 7

$A=\frac{3}{7}B$

Now,

Investment of A - Investment of B = Investment of C = Rs. 8000

$\frac{3}{7}B-B=8000 \ \frac{-4B}{7}=8000 \ B = -14000$

Since money can't be negative, so neglecting the negative sign we will have

B = Rs. 14000

Given:

The following bar graph shows the percentage of expenditure on different items by a person in a particular year.

Solution:

Percentage of expenditure on medicine & transport = (11+10)% = 21%

Total amount spent by the person during the year = Rs. 60000

The amount spent on medicine and transport will be,

$=\frac{21}{100}\times60000\ =12600$

Given:

The difference between the circumference and the diameter of a circular field is 60 m.

The cost of covering the ground is Rs. 500 per square meter.

Concept:

Area of a circle with radius r = $\pi r^2$

Circumference of a circle with radius r = $2 \pi r$

Diameter of a circle D = 2r

$\pi = \frac{22}{7}$

Total cost = Area of the circular ground X Rate per m²

Solution:

Circumference of the circle ($2 \pi r$) - Diameter (D = 2r) is 60 m

$2 \pi r - 2r =60 \ r[\pi-1]=30 \ r[\frac{22}{7}-1]=30\ r=30 ×\frac{7}{15}\ r=14 \ m$

Area of a circle with a radius of 14 m 

⇒ 22/7 × 14²

⇒ 616 m²

The cost of covering the ground is Rs. 500 per square meter.

⇒  Rs. (616 X 500)

⇒  Rs. 308000

∴ The answer is Rs. 308000.

Given:

A circle of radius 56 cm.

A rectangle of length and breadth in the ratio 7 ∶ 22 respectively.

The area of ​​the circle is equal to the area of ​​the rectangle.

Concept:

Area of a circle with radius r = $\pi r^2$

Area of a rectangle with length L and breadth B = $L \times B$

The perimeter of the rectangle = $2[L+ B]$

Solution:

Area of a circle with radius 56 cm,

$=\frac{22}{7}[56]^2 \ =9856 \ cm^2$

The length and breadth of the rectangle are in a ratio 7: 22

L : B = 7 : 22

$\frac{L}{B}=\frac{7}{22} \ L =\frac{7B}{22}$

Area of the rectangle,

$\frac{7B}{22} \times B= \frac{7B^2}{22}$

Since the area of ​​the circle is equal to the area of ​​the rectangle.

$\frac{7B^2}{22}=9856 \ B^2=30976 \ B = 176 \ cm$

L = 56 cm

The perimeter of a rectangle,

$=2[L+ B] \ =2[176+56] \ =464 \ cm$

Given:

The following line graph shows the total income of a family for two consecutive years.

Concept:

Percentage Increase $= \frac{Final \ Value -Initial \ Value}{Initial \ Value} \times 100 \ \%$

Solution:

Total income of the family in the year 2017,

= 90,000 + 50,000 + 20,000 + 25,000 + 10,000

= 1,95,000

Total income of the family in the year 2018,

= 95,000 + 55,000 + 25,000 + 30,000 + 5,000

= 2,10,000

Percentage Increase

 $= \frac{Final \ Value -Initial \ Value}{Initial \ Value} \times 100 \ \% \ = \frac{2,10,000 -1,95,000}{1,95,000} \times 100 \ \% \ = \frac {15,000}{1,95,000} \times 100 \ \% \ =\frac{1500}{195} \ \% \ =7.6923 \ \%$

Hence, option 2 is correct.

Given:

Sudhakar can finish a work in 15 days and Bina can finish 1/5 of the same work in 6 days.

Concept:

A person can finish a work in N days then,

Work done in a day = $\frac{1}{N}$

Solution:

According to the question,

Sudhakar can finish work in 15 days

Work done by Sudhakar in one day = $\frac{1}{15}$

Bina can finish 1/5 of the same work in 6 days.

Work done by Bina in one,

 $\frac{\frac{1}{5}}{6}= \frac {1}{30}$

Work done by Sudhakar and Bina together in one day,

$=\frac{1}{15}+\frac{1}{30}\ =\frac{3}{30}\ =\frac{1}{10}$

The Time taken by Sudhakar and Bina to finish $\frac{3}{5}$ of total work will be,

$=\frac{\frac{3}{5}}{\frac{1}{10}} \ =6$

Given:

The sides of a quadrilateral are in the ratio of 3 ∶ 4 ∶ 6 ∶ 8.

The perimeter of the quadrilateral is 84 cm.

Concept:

The perimeter of the quadrilateral = Sum of the sides

Solution:

The sides of a quadrilateral are in the ratio of 3 ∶ 4 ∶ 6 ∶ 8.

Perimeter = Sum of all the sides.

⇒ 3x + 4x + 6x + 8x = 84

⇒ 21x = 84

⇒ x = 4

Length of the longest side,

⇒ 8x = 8 × 4

⇒  32 cm 

∴ The answer is 32cm.

Given:

The maximum marks in Mathematics were 300.

Raman got 72% marks.

Concept:

Value of P% of given value = $\frac{P}{100}\times The \ value$

Solution:

According to the question,

Raman got 72% marks.

72% of 300 = $\frac{72}{100} \times 300=216$

Given:

Shyam wants to deposit Rs. 5000 for three years.

The compound interest rate received for these years will be 20%, 30%, and 10% respectively.

Concept:

For a principal amount, P compounded annually for 3 years at rates of r₁, r₂, and r₃ 

Amount  $=P[1+ \frac{r_1}{100}][1+ \frac{r_2}{100}][1+ \frac{r_3}{100}]~$

Solution:

Principal amount = Rs. 5000

r1 = 20%

r2 = 30% 

r3 = 10%

The required Amount will be,

$=5000[1+ \frac{20}{100}][1+ \frac{30}{100}][1+ \frac{10}{100}] \ =5000[\frac{120}{100}][\frac{130}{100}][\frac{110}{100}] \ =5000[\frac{12}{10}][\frac{13}{10}][\frac{11}{10}] \ =5 \times 12\times 13\times 11 \ =8580$

• The possessive case shows ownership.
• When the noun is singular, the Possessive case is formed by adding -'s to the noun.
• Example - The boy's book, the king's crown.
• When the noun is Plural, and ends in 's, the possessive case is formed by adding only an apostrophe.
• Example - Boys' school, horses' tails.
• Fontanel is an anatomical feature of the infant human skull comprising soft membranous gaps (शिशु मानव खोपड़ी की एक शारीरिक विशेषता है जिसमें नरम झिल्लीदार अंतराल होते हैं)
• An infant is born with two major soft spots on the top of the head called fontanels.

• In the given sentence, the phrasal verb 'dispose of' is used to imply that they will have to get rid of the mice in the attic.
• Correct sentence: We will have to dispose of the mice in the attic.

Hence, the correct answer is option (1).

Confusion Points 

• The correct phrase is "dispose of," not "dispose off." "Dispose of" is the standard and idiomatic phrase used to express the act of getting rid of something. "Dispose off" is not grammatically correct.
• The word "dispose" is a transitive verb, which means it requires an object.
• In this case, the object is "the mice in the attic."
• When using "dispose" in the sense of getting rid of something, it is followed by the preposition "of" to indicate what is being disposed of.
• So the correct phrase is "dispose of," and the correct sentence is: "We will have to dispose of the mice in the attic."

The correct answer is 'laudable'.

Key Points

• The word 'laudable' means deserving to be appreciated, praised or admired (सराहने योग्य; प्रशंसनीय, सराहनीय)

The correct answer is 'of the most famous outlaw'.

Key Points

• The error lies in Part (2) of the sentence.
• The 'one of' is a singular term and generally used to talk about a noun or a pronoun.
• The noun or a pronoun used after the phrase “one of” is always in the plural form ( as we are talking of one person/place/thing out of many)
• Example - This is one of the most robust findings in social science, and also one of the most ignored.
• Thus, the noun 'outlaw' must be in the plural form i.e., 'outlaws'.
• Correct sentence: Billy the Kid was one of the most famous outlaws of America's early history.

Hence, the correct answer is option (3).

The correct answer is 'Large personal library of music'.

Key Points

• It is evident from the above line that for quite a number of years the selection music for each film program rested entirely in the hands of the conducter or leader of the orchestra.
• At first, the music played bore no special relationship to the films; an accompaniment of any kind was sufficient.
• It is evident from the above line that during the initial time the music played bore no special relationship to the films; an accompaniment of any kind was sufficient.
• Accustomed though we are to speaking of the films made before 1927 as "silent," the film has never been, in the full sense of the word, silent. From the very beginning, music was regarded as an indispensable accompaniment.
• It is evident from the above lines that even as early as the silent films era, music has always accompanied the films.
• Thus, the incorrect option is 'Conductors were prioritized to be shown the films before hand so they could compose and practise meaningful music.'

Hence, the correct answer is option (4).

The correct answer is 'Birth of a nation'.

• It is evident from the above line that the films made before 1927 were regarded as 'silent films'.
• Thus, the correct answer is 'Silent films'.

Hence, the correct answer is option (3).
