Let the CP of headphone be Rs.

So, CP of smartphone be Rs.

So, total SP Rs.

SP of smartphone Rs.

SP of headphone Rs. Rs.

So, profit on the sale of headphone Rs. Rs.

According to the question,

∴

Given,
Mean of 60 observation = 66
Error = 24 was wrongly taken as 42.

Total sum of 60 observations
= 3960
Correct sum of 60 observations 
= 3942
The correct mean   
= 65.7
∴ The correct mean is 65.7.

Given: Number 2632A4878 is divisible by 9.
As we know,
The Sum of all digits should be divisible by 9 .
The number is 2632A4878 .
⇒ 2 + 6 + 3 + 2 + A + 4 + 8 + 7 + 8
⇒ 40 + A
Put A = 5
⇒ 40 + 5 = 45
⇒ 45 is divisible by 9
The value of ' A ' is 5.

Given, Chords AB = 8 cm and CD = 6 cm
Then, AE = EB = 4 cm and CF = FD = 3 cm
EF = 1 cm
Let OE = x cm
Then, OF = (x + 1) cm
OA = OC = r cm  (∵ radius)
From ΔOAE, By pythagoras theorem
OA² = AE² + OE²
⇒  r² = 4² + x²
⇒  x² = r² – 16  ...(i)
From ΔOCF, By pythagoras theorem
OC² = CF² + OF²
r² = 3² + (x + 1)²
(x + 1)² = r² – 9 ...(ii)
By equation (ii) – (i),
(x + 1)² – x² = r² – 9 – r² + 16
⇒  x² + 1 + 2x – x² = 7
⇒  2x = 7 – 1 = 6
⇒  x = 3 cm
∴  From equation (i),
9 = r² – 16
⇒  r² = 25
⇒  r = 5 cm

Given:
Total number of boys in a college = 116% of the total number of girls in a college
Let the total number of girls in a college be 100.

Total number of boys

The ratio of the total number of boys to girls =  116/100 = 29 ∶ 25

∴ The ratio of the total number of boys compared to girls in that college is 29 ∶ 25.

Given,

As we know that componendo and dividendo rule is given as,

Then applying this rule, we get

As we know,

Given:
mnx - 10mn - 30mx - 45nx + 300m + 450n + 1350x - 13500 = 0
⇒ mn (x - 10) - 30m (x - 10) - 45n (x - 10) + 1350 (x - 10) = 0
⇒ (x - 10) (mn - 30m - 45n + 1350) = 0
⇒ (x - 10) {n (m - 45) - 30 (m - 45)} = 0
⇒ (x - 10) (n - 30) (m - 45) = 0
Therefore, x = 10, m = 45 and n = 30
'a', 'n' and '50' are in GP.
Therefore,

⇒ a = 18
m = yc²
⇒ 45 = 1 × 45 or 5 × 9
'm', 'y' are distinct natural numbers so, y = 5 and c² = 9
a = bc²

Putting all the values in a table we get,

For alloy Q : Let the ratio of Zn : C : L = 30x : 10x : Lx
The difference between the quantity of Copper and Lead in alloy 'Q' is 270 gm.
Therefore, 10x - Lx = 270 ...(a)
The difference between the quantity of Zinc and Copper in alloy 'Q' is 600 gm.
Therefore, 30x - 10x = 600
⇒ 20x = 600
⇒ x= 30
Putting this value of x in equation (a) we get

⇒ L = 1
The quantity of Lead in alloy 'Q' = Lx = 30 gm
So, the correct answer is 30 gm.

The sum of the linear pair angles is equal to .

Let and are and .

(Linear pair)

The value of is .

We know that

From the given data,

We can assume and

The pattern followed here is,

Thus, QAS is the correct answer.

So, X is the wife of A.

The pattern followed here is:

Thus, “EFKH” is the correct answer.

The pattern followed here is;

Outer circle number (Inner circle number next number in inner circle clockwise.

The proper sequence is: SQPR

Reason:

• Sentence S will be the first sentence of the sequence because it tells what happens often with the green revolution.
• Sentence Q will come after S because it mentions how the green revolution is characterized.
• Sentence P will come after Q because it mentions the effect of a high-yielding variety of seeds and fertilizers.
• The sentence 'R' is the concluding part because it has mentioned the final result of the green revolution.

The correct sentence is:

The green revolution, which is often characterized by the introduction of a high-yielding variety of seeds and fertilizers undoubtedly increased the productivity of land considerably.

The use of pronoun "his" is incorrect in part (C) as it is referring to plural subject which is "politicians". Therefore, plural pronoun "their" should be used here.

'Than' is used to introduce the second element in a comparison.

Here comparision between earth and equator is being done. So, as per context of the passage 'than' is appropriate here.

Raining cats and dogs: very heavily raining.

For example:

• It’s raining cats and dogs I am worried about how my kids will reach home.
• It rains cats and dogs when the Monsoon comes to India.

​​​From the above lines, we can say that Very heavy rain is the correct meaning of the given idiom.

In option (D), the usage of 'they' is incorrect.

'One' will be used instead of 'they'.

Whenever the subject of the sentence is 'one' the pronoun should be used according to the subject of the sentence i.e., 'one'.

Let's see an example:

​One should do one's duty sincerely.

The correct sentence will be: 

One should be careful to re-read what one has written.

The correct order is: SQRP

Reason:

• While arranging the parts of the sentence given in options, we have to find some grammatical or contextual connections between them.
• Initial sentence 'Climate change due' ends with 'due' and we know that 'to' is used after 'due'. Hence, the first sentence would be 'S'. So, either 'A' or 'C' would be the answer.
• 'Q' would be the next sentence because it explains what climate change has done.
• 'R' would be the next sentence because 'R' and 'P' are contextually connected and 'P' follows 'R'.

The correct sentence is:

Climate change due to global warming causing changes in rainfall is the new challenge to rice production and a matter of concern for agrarian societies.

Correct Sentence: In addition to our low annual fee, you will receive a 20% discount if you sign up this week.

"In addition to" means- besides; as well as.

"In addition to" is used to mention another item connected with the subject which are discussing.

Correct sentence is: Peter wants to come with us this summer.

• The sentence talks about peter who wants to spend summer. 
• Here, peter wants to accompany them this summer. 'with' means accompanied by (another person or thing). 
• So, 'with' is the correct word for the blank.

Right to equality (Articles 14-18):

1. Equality before the law and equal protection of laws (Article 14).

3. Equality of opportunity in matters of public employment (Article 16).
4. Abolition of untouchability and prohibition of its practice (Article 17).
5. Abolition of titles except military and academic (Article 18).

Thus, Right to equality is violated due to practice of untouchability in India.
