The correct answer is 'C'.

Key Points

• The error lies in Part C of the sentence.
• In the given sentence, 'pair' is a collective noun.
• If the collective noun refers to the group as a unit, then it takes a singular verb.
• Example: This organization puts on a barbecue every summer.
• ​'Pair of diamond earrings' is a singular collective noun, therefore a singular verb should be used with it.
• Therefore, the plural helping verb 'are' should be replaced by a singular helping verb 'is'.
• Hence, the correct answer is 'C'.

Correct sentence: The pair of diamond earrings, which you bought me yesterday, is expensive.

​​​​

Additional Information

• A collective noun is used to refer to an entire group of persons, animals, or things; it, therefore, includes more than one member.
• A plural collective noun takes a plural verb.
• Example: Families enjoy this restaurant.
• ​A singular collective noun usually takes a singular verb.
• Example: Our family enjoys this restaurant.
• ​When all the members of a collective noun are performing an action as a unit (and that’s usually the case), use a singular verb.
• When the members of a collective noun are performing an action as individuals, use a plural verb.
• In this case, all or some members of the group are doing something independently of the other members; the group is not acting together as a unit.

The correct answer is 'B'.

Key Points

Additional Information

The correct answer is the Pacific Ocean.

Key Points 

The International Date Line passes through the Pacific ocean.​ 

• The International Date Line(IDL)
• The international date line is an imaginary line that passes through the Pacific Ocean
• Along with the IDL, the date changes by exactly one day when it is crossed.
• A traveler crossing the dateline from West to East gains a day while crossing the dateline from East to West loses a day.
• Why there is a gain or loss of day?
• 180o E is GMT +12hrs and 180o W is GMT -12hrs, hence the difference between 180o E and 180o W is 24hrs.
• That is time difference on either side of IDL is 24hours, so the date changes as soon as one crosses IDL.
• Why it passes through the water body only?
• If the IDL passes through the land, then two regions of the same Island country or Island group would fall under different date zones. Thus, to avoid any confusion of date, IDL is drawn from the water body only, that's why it is in the Zig-zag manner.

• Origami - Ori meaning "folding", and kami meaning "paper"  is the art of paper folding, which is often associated with Japanese culture.
• In modern usage, the word "origami" is used as an inclusive term for all folding practices, regardless of their culture of origin. The goal is to transform a flat square sheet of paper into a finished sculpture through folding and sculpting techniques.
• Modern origami practitioners generally discourage the use of cuts, glue, or markings on the paper. Origami folders often use the Japanese word kirigami to refer to designs which use cuts.

Additional Information

• In Japan, the earliest unambiguous reference to a paper model is in a short poem by Ihara Saikaku in 1680 which mentions a traditional butterfly design used during Shinto weddings.
• Folding filled some ceremonial functions in Edo period Japanese culture; noshi were attached to gifts, much like greeting cards are used today. This developed into a form of entertainment; the first two instructional books published in Japan are clearly recreational.
• In the early 1900s, Akira Yoshizawa, Kosho Uchiyama, and others began creating and recording original origami works. Akira Yoshizawa in particular was responsible for a number of innovations, such as wet-folding and the Yoshizawa–Randlett diagramming system, and his work inspired a renaissance of the art form. During the 1980s a number of folders started systematically studying the mathematical properties of folded forms, which led to a rapid increase in the complexity of origami models.

Given:

Speed of A = 36 km/hr = 36 × 5/18 = 10 m/sec

Speed of B = 54 km/hr = 54 × 5/18 = 15 m/sec

Speed of C = 18 km/hr = 18 × 5/18 = 5 m/sec

Formula used: 

Speed = Distance/Time

Calculation:

Time taken by A to complete 1 round = 1200/10 = 120 seconds

Time taken by B to complete 1 round = 1200/15 = 80 seconds

Time taken by C to complete 1 round = 1200/5 = 240 seconds

∴ The meeting time will be LCM of (120, 80, 240) i.e = 240 seconds

Given:

Time taken by X to complete the work = 10 days

Time taken by Y to complete the work = 15 days

They both work together for 2 days

Formula used:

Efficiency = Total work/Time taken

Calculation:

LCM of 10 and 15 = 30 = Total work

Efficiency of X = 30/10 units/day

⇒ 3 units/day

Efficiency of Y = 30/15 units/day

⇒ 2 units/day

Total work done by X and Y together in 2 days = (3 + 2) × 2 units

⇒ 10 units

Work remaining = (30 – 10) units

⇒ 20 units

Time taken by Y to complete the work = 20/2 udays

⇒ 10 days

∴ Time taken by Y to complete the remaining work is 10 days

Given:

Speed of A = 45 km/hr

Speed of B = 60 km/hr

A starts at 9 ∶ 00 AM and B starts at 10 ∶ 00 AM

They meet at half distance while travelling in the opposite direction

Concept used:

Distance = Speed × Time

Calculation:

Let the time taken by B to reach half the distance be x hours

Time taken by A to reach half the distance will be x hours + 1 hour = (x + 1) hours

As, they have traveled half distance, i.e they have traveled equal distance

Half distance travelled by A = 45 × (x + 1)

Half distance traveled by B = 60 × x

45x + 45 = 60x

⇒ 15x = 45

⇒ x = 3

Distance travelled by A = 45 × (3 + 1) = 45 × 4 = 180

∴ Distance traveled by A is 180 km

Given:

Average age of 2 grandparents = 75

Average of 3 parents = 45

Average of 4 grandchildren = 25

Formula used:

Sum of ages = Average age × Number of persons

Calculation:

Sum of ages of 2 grandparents = (75 × 2) years

⇒ 150 years

Sum of age of 3 parents = (45 × 3) years

⇒ 135 years

Sum of ages of 4 grandchildren = (25 × 4) years

⇒ 100 years

Total age of family = (150 + 135 + 100) years

⇒ 385 years

∴ Total age of family is 385 years

Given:

Speed from A to B = 20 km/hr

Speed from B to A = 30 km/hr

Formula used:

Average speed = Total distance/Total time

Calculation:

Let the distance between A to B be x km

So according to question,

Average speed = 2x/(x/20 + x/30) 

⇒ Average speed = 2x/(5x/60)

∴ Average speed = 24 km/hr

Given:

40% girls and 92.5% girls pay fees

60% boys and 85% of boys pay fees

Calculation:

Let the total number of the students be 100

Number of girls = 40 

Number of girls paid fees = 92.5% of 40 = 37

Number of boys = 60 

Number of boys paid fees = 85% of 60 = 51

Number of student that didn't paid the fees = 100 - (37 + 51) = 12

And according to question,

12 = 180 

⇒ 1 = 15

So the number of students = 15 × 100 = 1500

Number of students pay fees = 15 × 88 = 1320

∴ The number of students that gets scholarship = (1/2) × 1320 = 660

Given:

A's pocket money 30% of the total amount and expense = 20% of its pocket money

A's saving = Rs. 144

B's pocket money = 20% of total amount and expense = 50% of its pocket money

Calculation:

Let the total amount be 100

So pocket money of A = 30

A's expenses = 20% of 30 = 6

Saving of A = 30 - 6 = 24

But according to the question,

24 = Rs. 144

⇒ 1 = Rs. 6

So the total amount = 100 × 6 = Rs. 600

Pocket money of B = 20% of 600 = 120

Expense of B = 50% of 120 = Rs. 60

∴ Saving of B = 120 - 60 = Rs. 60

Alternate Method

Let total amount be Rs x.

Saving of A = 144 = x × 30% × 80%

x = Rs 600

Saving of B = x × 20% × 50% = 600 × 1/10

Saving of B is Rs 60.

Given:

Cost of 12 shirts = Selling price of 8 shirts

Formula used:

Profit% = (Profit/CP) × 100%

Calculation:

Let the cost of 12 shirts be Rs. 12

SP of 8 shirts = Rs. 12

Cost of 8 shirts = Rs. 8

Gain = Rs. (12 – 8)

⇒ Rs. 4

Gain% = (4/8) × 100%

⇒ 50%

∴ The profit percentage in this transaction is 50%

Given:

24 Men and 6 women can complete the work in 10 days

6 men and 6 women can complete the work in 12 days

Calculation:

(24M + 6W) × 10 = (6M + 6W) × 12

⇒ 240M + 60W = 72M + 72W

⇒ 168M = 12W

⇒ M : W = 1 : 14

Total work = (24 × 1 + 6 × 14) × 10 = 1080 units

Time in which 4 men and 1 women will complete the work = 1080/(4 × 1 + 14 ) = 60 days

∴ 4 men and 1 woman can complete the work in 60 days

Given:

[(0.3)3 + (0.6)3] ÷ [(0.6)3 + (0.2)3]

Calculation:

[(0.3)3 + (0.6)3] ÷ [(0.6)3 + (0.2)3]  

⇒ [0.027 + 0.216] ÷ [0.216 + 0.008]

⇒ 0.243/0.224 = 243/224

∴ 243/224

Given:

A sum of amount becomes 7 times in 20 years at simple interest

Formula used:

S.I = PRT/100

Amount = Principal + S.I

Calculation:

Let the principal be Rs. x

Amount = Rs. 7x

S.I = Rs. (7x – x) 

⇒ Rs. 6x

Now, according to the question

(x × R × 20)/100 = 6x

⇒ R = 6 × 5%

⇒ 30%

∴ The rate of simple interest is 30%

Concept:

$\frac{a}{{(\frac{b}{c})}};=\frac{ac}{b}$

Calculation:

$\frac{7}{{(\frac{8}{9})}};$ - $\frac{8}{{(\frac{9}{7})}};$ 

By using the above concept,

⇒ 63/8 - 56/9

⇒(63 × 9 - 56 × 8)/72

⇒ (567 - 448)/72

∴ $\frac{7}{{(\frac{8}{9})}};$- $\frac{8}{{(\frac{9}{7})}};$ = 119/72

Given:

Total number of pens = 180

Rate of a pen = Rs. 120 per pen

Expenditure on Transportation and packaging = Rs. 2160

Marked price of each pen = Rs. 150

Discount = 4%

Formula used:

Profit% = (Profit/CP) × 100%

SP = MP × [(100 – Discount%)/100]

Calculation:

Cost of 180 pens = Rs. (180 × 120)

⇒ Rs. 21600

Total cost = Rs. (21600 + 2160)

⇒ Rs. 23,760

Marked price of 180 pens = Rs. (150 × 180)

⇒ Rs. 27000

SP = RS. 27000 × (96/100)

⇒ Rs. 25,920

Gain = Rs. (25,920 – 23,760)

⇒ Rs. 2160

Gain% = Rs. (2160/23,760) × 100%

⇒ 9.09%

∴ The overall gain percentage is 9.09%

Shortcut Trick

Simplify ratios first: A ∶ B = 3 ∶ 6 = 1 ∶ 2 and B ∶ C = 7 ∶ 28 = 1 ∶ 4.

Make B common: Multiply (1 ∶ 2) by 1 and (1 ∶ 4) by 2.

A ∶ B = 1 ∶ 2 and B ∶ C = 2 ∶ 8.

Combined ratio A ∶ B ∶ C = 1 ∶ 2 ∶ 8.

∴ The correct answer is 1 ∶ 2 ∶ 8.

Alternate Method

Given:

Ratio A ∶ B = 3 ∶ 6

Ratio B ∶ C = 7 ∶ 28

Calculations:

⇒ A/B = 3/6 = 1/2

⇒ B/C = 7/28 = 1/4

⇒ To combine, we need the value of B to be the same in both ratios.

⇒ LCM of B values (2 and 1) is 2.

⇒ A ∶ B = 1 ∶ 2

⇒ B ∶ C = (1 × 2) ∶ (4 × 2) = 2 ∶ 8

⇒ Therefore, A ∶ B ∶ C = 1 ∶ 2 ∶ 8

∴ The correct answer is 1 ∶ 2 ∶ 8.

Additional Information

Given:

7000 invested for first 3 years

After 3 years 3000 more invested 

Total interest after 8 years = 4970

Formula used:

Simple interest = (Principal × Rate × Time)/100

Calculation:

Let the rate of interest be R% per annum

So according to question,

(7000 × R × 3)/100 + (10000 × R × 5)/100 = 4970

⇒ 210R + 500R = 4970

⇒ 710R = 4970

⇒  R = 7%

∴ Rate of interest = 7%

Given:

Average salary of 6 person = Rs. 15000

Average salary of first 5 person = Rs. 12000

Formula used:

Average = Sum of Total observation/Number of observation

Calculation:

Total salary of 6 persons = 15000 × 6

⇒ Rs. 90000

Total salary of first 5 person = 12000 × 5

⇒ Rs. 60000

So, The salary of 6^th person = 90000 - 60000

⇒ Rs. 30000 

∴ The salary of the 6^th person is Rs. 30000.

Given:

From Surat to Jaipur speed = x km/hr

From Jaipur to Surat speed = y km/hr

Formula used:

Average speed = Total distance/Total time

Calculation:

So according to the question,

Average speed = 2D/(D/x + D/y)

∴ Average speed is 2xy/(x + y)

Concept:

Error % = [(Approximate Value – Exact Value) / Exact Value] × 100

Calculation:

Let the number be y

Error = |2y/5 - 3y/5| = y/5

By using the above formula, 

Error % =  {(y/5)/(2y/5)} × 100 

⇒ Error % = (1/2) × 100 = 50%

∴ Percentage error in the calculation is 50 %.
