The correct answer is 'cheerful'.

Key Points

• In high spirits is an idiom that means 'very happy and excited' (बहुत खुश और उत्साहित).
• Example - *All the children were in high spirits (*उच्च उमंग के साथ ) on the last day of school.
• So, cheerful is the most appropriate meaning of the idiom given in bold in the following sentence.
• Hence, option 1 is the correct answer.

The correct answer is 'significant role in enduring the trends'.

Key Points

• The given sentence points out the importance that a person's family has in maintaining familial trends and age-old traditions.
• Passive, futile and docile give a meaning which implies that the family does not have a big role to play in maintaining old traditions.
• But, by using 'significant', this concept is established.
• Hence, option3 is the correct answer.

Correct sentence - One’s family plays a very significant role in enduring the trends and age-old traditions.

The correct answer is 'Bhavani made a trip to the village temple yesterday.'

Key Points

• The given sentence is in passive voice. As per the question we have to change it into active voice.
• The structure of the given sentence is as follows:
• Subject (objective case) + was + past participle + by Object (subjective case) (Passive voice) + adjunct
• Subject + past participle + Object (Active voice) + adjunct
• Example: 
• A large house was built by her. (Passive voice)
• She built a large house. (Active voice)
• The subject of the given sentence is ‘Bhavani’.
• The object of the given subject is ‘trip’.
• The subject will be put in place of the object and the object will be put in place of the subject.
• was made will be changed to made.
• Adjunct is a word or phrase that constitutes an optional element or is considered of secondary importance in a sentence
• In the given sentence, to the village temple yesterday is the adjunct.
• Thus, the correct answer is option 2.

The correct answer is 'bigger'.

Key Points

• From the given options we need to select the appropriate adjective for the given blank to describe the comparison between the dreams of the subject (He) and his friends.
• We need to select the comparative degree of adjective as the comparison is happening between two objects.
• Now big is an adjective that has one syllable.
• Adjectives with one syllable can form the comparative by adding -er.
• So, bigger is the comparative degree of the adjective and is appropriate for the given blank.
• Hence, option 1 is the correct answer.

Correct sentence - He dreams bigger than his friends.

Additional Information

• If the adjective has a consonant + single vowel + consonant spelling (fat, big etc), the final consonant must be doubled before adding the ending.

The correct answer is 'CBDA'.

Key Points

While arranging the parts of the passage, we should find some grammatical or contextual connections between them. Also, the first sentence of a passage is usually independent and introduces a topic. The second one provides more information about it. 

• Sentence C is the independent sentence and introduces the topic which relates to what the author did during a summer before going to college.
• So, sentence C is the first sentence after rearrangement. It explains where the author worked and why.
• Sentence B describes what the author did during Sundays and talks about one particular incident on a Sunday. Hence, B follows C.
• Sentence D explains the author's feeling regarding segregation which he faced once coming back from the farm. So, it should come after sentence B, to maintain continuity on the topic.
• Sentence A is the concluding statement of the passage as it provides further information regarding the author's feelings.

Thus, the correct order after rearrangement is option 3 i.e. CBDA.

So, the correct paragraph is : (C) Just before going to college I went to Simsbury, Connecticut, and worked for a whole summer on a tobacco farm to earn a little school money to supplement what my parents were doing. (B) One Sunday, we went to church in Simsbury, and we were the only Negroes there and on Sunday mornings I was the religious leader and spoke on any text I wanted to 107 boys. (D) After that summer in Connecticut, it was a bitter feeling going back to segregation and it was hard to understand why I could ride wherever I pleased on the train from New York to Washington and then had to change to a Jim Crow car at the nation’s capital in order to continue the trip to Atlanta. (A) The first time that I was seated behind a curtain in a dining car, I felt as if the curtain had been dropped on my selfhood and could never adjust to the separate waiting rooms, separate eating places, separate rest rooms, partly because the separate was always unequal, and partly because the very idea of separation did something to my sense of dignity and self-respect.

Break the series in 5 letters consist of 1 code, now notice the pattern that last 4 letters are same in every code, and the first letter get changed by the very next of it in the English alphabets.  Like S is changed by T, T is changed by U and  U is changed by V.

So the series is as follows,

Given: S _ O Z Q T L O _ Q U _ O _ Q V L O Z _

1) L Z L Z Q → S L O Z Q - T L O Z Q - U L O Z Q - V L O Z Q

2) Z L Z Q L → S Z O Z Q - T L O L Q - U Z O Q Q - V L O Z L

3) Z L Q L Z → S Z O Z Q - T L O L Q - U Q O L Q - V L O Z Z

4) L Z Q Z L → S L O Z Q - T L O Z Q - U Q O Z Q - V L O Z L

Correct sequence of given series is:  S L O Z Q, T L O Z Q, U L O Z Q, V L O Z Q

Therefore,  the correct answer is "L Z L Z Q".

Hence, the correct option is option(1).

Given:

Markup% = 45%

Discount% = 21%

Formula used:

Discount%= (MP - SP)/MP × 100

Selling Price (SP) = Marked price (1 - Discount%/100)

Profit% = (SP - CP)/CP × 100

Calculation:

Let the cost price be Rs. x

⇒ Marked price = x + (45/100) × x = 1.45x

⇒ SP = 1.45 × (1 - 21/100)

⇒ SP = 1.45 × (0.79) = 1.1455x

Now Profit%

⇒ Profit% = (1.1455x - x)/x × 100

⇒ Profit% = 0.1455 × 100 = 14.55% ~ 15%

∴ The Profit% is 15%

Shortcut Trick

Divisibility of 7

Concept used 

The divisibility rule of 7 states that

Pick the last digit of a number, multiply it by 2,  

Subtract the product from the rest of the number to its left. If the difference is 0 or a multiple of 7, then the given number is divisible by 7 

Calculations:

According to the concept,

We will check if the numbers are divisible by 7

⇒ 3739 = 373 - 9 × 2 = 373 - 18 = 355 [not a multiple of 7]

⇒ 3661 = 366 - 1 × 2 = 364 [multiple of 7]

⇒ 3659 = 365 - 9 × 2 = 365 - 18 = 347 [not a multiple of 7]

⇒ 3915 = 391 - 5 × 2 = 391 - 10 = 381 [not a multiple of 7]

∴ The number divisible by 7 is 3661

Given:

Marked up% (MP) = 25% 

Profit% = 20%.

Concept:

SP = [(100 + gain%)/100] × C.P

Calculation:

Let the cost price of the article is 100.

According to the question

The selling price of the article 

⇒ SP = [(100 + 20)/100] × 100 = 120

The Marked price of the article is

⇒ [100 + (100 × 25%)]

⇒ 100 + 25 = 125

Also,

The selling price of the article is

SP = [125 - (125 × x%)]

⇒ x = [(125 - 120)/125] × 100

⇒ x = 5/125 × 100 = 4%

∴ The discount should be given of 4%.

Shortcut Trick

Calculations:

Let the mean price of the mixture be Rs. x/kg and the ratio of the two varieties be R

72 = (120/100) × x 

⇒ 6x = 360

⇒ x = 360/6 = Rs. 60/kg

Using the concept,

⇒ R = (80 - 60)/(60 - 45)

⇒ R = 20/15

⇒ R = 4/3 = 4 : 3

∴ The ratio in which the two varieties must be mixed is 4 : 3.

Shortcut Trick

Given:

The average score of 50 students is 66

40% are girls and the rest are boys.

The average score of the boys is 20% less than that of the girls.

Formula used:

Average = (Sum of Values/Number of Values)

Calculation:

According to the question:

Total boys in class = 50 × 60/100 = 30

⇒ Rest girls 50 - 30 = 20

The average score of the boys is 20% less than that of the girls.

Average score of boys = 80/100 × Average score of girls

The average score of girls/Average score of boys = 5/4

Let the Average score of girls be 5x And the Average score of boys be 4x

Now, 

66 = (5x × 20 + 30 × 4x)/50

⇒ 66 × 50 = 100x + 120x

⇒ 3300 = 220x

⇒ x = 3300/220 = 15

Average score of girls = 5x = 5 × 15 = 75.

∴ The Average score of girls is 75.

Now the value of land after 2 years 

Amount = 243000 (1 + 0.5)2 

⇒ A = 243000 (1.5)2 

⇒ A = 243000 × 2.25 = 546750

∴ The value (in ₹) of the land after 2 years, from the time Q bought the land from P is Rs. 546750.

Alternate Method

The Land's value depreciated at 25%, So after 2 year,

The value from 4² = 16 unit becomes 3³ = 9 unit

So, after two years of depreciation, the value of the land is

⇒ (432000/16) × 9 = 243000

Next two years the land's value appreciation is 50%, after 2 years

The value from 22 = 4 unit becomes 33 = 9 unit

So, after two years of appreciation, the value of the land is,

⇒ 243000/4 × 9 = 546750

∴ The correct answer is 546750

Shortcut Trick

Net Multiplier = (Markup Factor) × (Discount Factor) × (Weight Factor)

Net Multiplier = (130 / 100) × (90 / 100) × (1000 / 870)

Net Multiplier = 1.3 × 0.9 × (100 / 87) = 1.17 × (100 / 87) = 117 / 87 = 39 / 29

Profit % = [(39 − 29) / 29] × 100 = (10 / 29) × 100 ≈ 34.48%

∴ The correct answer is 34.48%.

Alternate Method

Given:

Markup = 30%, Discount = 10%, Faulty weight = 870 g instead of 1000 g.

Formula Used:

Net Profit % = [(Total SP / Total CP) − 1] × 100

Let the Cost Price (CP) of 1 g of goods be ₹1.

⇒ Actual CP for the shopkeeper (for 870 g) = 870 × 1 = ₹870.

⇒ Marked Price (MP) for 1000 g = 1000 + 30% of 1000 = ₹1300.

⇒ Selling Price (SP) after 10% discount on MP = 1300 − (10 / 100) × 1300.

⇒ SP = 1300 − 130 = ₹1170.

⇒ Net Profit = SP − CP = 1170 − 870 = ₹300.

⇒ Net Profit % = (300 / 870) × 100.

⇒ Net Profit % = (30 / 87) × 100 = (10 / 29) × 100 ≈ 34.48%.

∴ The correct answer is 34.48%.

Additional Information

Dishonest Dealer Concept

Profit % due to weight fraud = [True Value − False Value] / False Value × 100. In this case, (1000 − 870) / 870 × 100.

Marked Price and Discount

Relationship: SP = CP × (1 + Markup %) × (1 − Discount %). This represents the price multiplier effect.

Successive Percentage Change

The effective percentage change for two successive changes x% and y% is [x + y + (xy / 100)]%.
