Given:

The Least Common Multiple (LCM) = 75

Highest Common Factor (HCF) = 5

Difference between LCM and HCF = 10

Formula used:

Product of two numbers = Product of their LCM and HCF

(a + b)² = (a – b)² + 4ab

Calculations:

Let the two numbers be a and b.

⇒ a × b = 5 × 75

⇒ a × b = 375

∵ a – b = 10

Also, (a + b)² = (a – b)² + 4ab

⇒ (a + b)² = (10)² + 4(375)

⇒ (a + b)² = 100 + 1500

⇒ (a + b)² = 1600

⇒ (a + b) = 40

Therefore, Sum of the two numbers = 40.

Given:

Discount percentage = 12.5%.

Selling Price = Rs. 5845

Calculations:

⇒ Discount = 12.5% × 100x = Rs. 12.5x

⇒ Selling Price = Rs. 100x - Rs. 12.5x = Rs. 87.5x

⇒ 5845 = 87.5x

⇒ x = 5845/87.5 = 66.8

⇒ Marked price = Rs. 100 × (66.8) = Rs. 6680

∴ The marked price of article is Rs. 6680

Given:

⇒ P(1 + (R/100))⁷ = 8P

⇒ (1 + (R/100))⁷ = 8

⇒ 1 + (R/100) = 8^1/7 --- (1)

Let Amount after T years be Rs. 4096P

⇒ P(1 + (R/100))^T = 4096P

⇒ (1 + (R/100))^T = 4096

Substituting (1) in above equation

⇒ (8^1/7)^T = 8⁴

⇒ (8^T/7) = 8⁴

⇒ T/7 = 4

⇒ T = 28

∴ In 28 years, the given principal will become 4096 times of itself.

Calculation:

As the given data in bar graph shows the ratio of expenditure to revenue for seven consecutive years

Revenue for year Y4 = Rs. 22500

For Y4, the ratio of expenditure to revenue = 0.9

Ratio of Expenditure to Revenue = 0.9 = 9 : 10

Let expenditure be Rs. 9x and Revenue be Rs. 10x

FORMULA USED:

Profit percentage = [(Revenue – Expenditure)/Expenditure] × 100

Calculations:

According to question,

⇒ 10x = 22500

⇒ x = 2250

⇒ Profit = Revenue - Expenditure

⇒ Profit = = Rs. 10x - Rs. 9x

⇒ Profit = = Rs. x

⇒ Profit = Rs. 2250

∴ The profit for year Y4 is Rs. 2250.

Important Points In this question we have provided the ratio of expenditure to revenue

Case 1 Y4

⇒ Expenditure/Revenue = 0.9

⇒ Expenditure/Revenue = 9/10

It means the numerator part is an expenditure, and the denominator part is revenue.

Profit = Revenue - Expenditure

Formula used:

Volume of the cylinder = π × r² × H

Volume of the cone = 1/3 × π × r² × h

Calculation:

   

Let the radius of the cone = r cm 

According to the Question,

Volume of the cone = Volume of the cylinder

⇒ 1/3 × π × r² × h = π × r² × H

⇒ 1/3 × π × r² × 16 = π × 10² × 48

⇒ r² = 10² × 3²

⇒ r = 30

∴ The Diameter of the base of the cone = 2 × 30 = 60 cm.

Given:

From the pie chart,

Total time taken in making one car = 1200 hours

Time taken in J3 = 20% of 1200

⇒ Required Average = 576/3

⇒ Required Average = 192 hours.

Shortcut Trick Profit% = [(Articles with CP − Articles with SP) ÷ Articles with SP] × 100 Profit% = [(80 − 50) ÷ 50] × 100 Profit% = (30 ÷ 50) × 100 = 60% ∴ The correct answer is 60%.

Alternate Method Given → CP of 80 articles = SP of 50 articles. Formulas: Profit = SP − CP | Profit% = (Profit ÷ CP) × 100

⇒ 80 × CP = 50 × SP ⇒ CP ÷ SP = 50 ÷ 80 = 5 ÷ 8 ⇒ Let CP = 5 units and SP = 8 units. ⇒ Profit = 8 − 5 = 3 units. ⇒ Profit% = (3 ÷ 5) × 100 = 60%. ∴ The correct answer is 60%.

Additional Information Cost Price (CP) and Selling Price (SP) Relation When the CP of 'x' articles equals the SP of 'y' articles, the profit or loss depends on whether x > y (profit) or x < y (loss). Profit Percentage Calculation Profit% is always calculated on the Cost Price unless specified otherwise. Formula: Gain% = [Gain ÷ CP] × 100.

Shortcut Trick

Let Y = 100.

X = 100 − 30 = 70

Z = 100 − 50 = 50

Required % = (Difference / X) × 100 = (20 / 70) × 100 = 200 / 7 = 28.57%

∴ The correct answer is 28.56%.

Alternate Method

Given:

X is 30% less than Y.

Z is 50% less than Y.

Let the value of Y be 100.

⇒ X = Y − (30% of Y)

⇒ X = 100 − 30 = 70

⇒ Z = Y − (50% of Y)

⇒ Z = 100 − 50 = 50

⇒ Difference between X and Z = 70 − 50 = 20

⇒ Percentage by which Z is less than X = (Difference / X) × 100

⇒ Required Percentage = (20 / 70) × 100

⇒ Required Percentage = 200 / 7 ≈ 28.56%

∴ The correct answer is 28.56%.

Additional Information

Percentage Change

Percentage less = (Difference / Higher Value) × 100. Percentage more = (Difference / Lower Value) × 100.

Base Change Rule

If A is p% less than B, then B is [p / (100 − p)] × 100% more than A.

Fraction to Percentage Conversion

1/7 is approximately 14.28%, so 2/7 is approximately 28.56%.

Calculations:

2A = 3B

⇒ A = 3B/2

⇒ 7C = 3B

⇒ C = 3B/7

⇒ A : B : C = 3B/2 : B : 3B/7

⇒ A : B : C = 21B :14B : 6B

⇒ A : B : C = 21 : 14 : 6

Given:

Length of the train = L m

Length of the first Bridge = 340 m

Time taken to cross first Bridge = 35 seconds

Length of the Second Bridge = 460 m

Time taken to cross second Bridge = 38 seconds

Concept:

When a train crosses a bridge, it travels a distance equal to its own length and the length of the bridge.

Common mistake:

These types of questions, the conversion of speed in meter/seconds into Km/hr should be done carefully.

Unit conversion from Km/hr to m/s, then multiply from 5/18.

Unit conversion from m/s to Km/hr, then multiply from 18/5.

FORMULA USED:

Speed = (Distance)/(Time)

CALCULATION :

The train crosses First bridge in 35 sec,

∵ Length of train + Length of First bridge = L + 340

⇒ Speed of train = (L + 340)/(35)

The train crosses Second bridge in 38 sec,

∵ Length of train + Length of Second bridge = L + 460

⇒ Speed of train = (L + 460)/(38)

According to Question,

Speed of train will be same

(L + 340)/(35) = (L + 460)/(38)

On solving we get,

⇒ Length of train, L = 1060 m

⇒ Speed of train = (1060 + 340)/(35)

⇒ Speed of train = (1400)/(35) = 40 m/s

⇒ Speed of train = 40 × 18/5 = 144 Km/hr

Formula used:

Mean = Sum of all observation/Total observation

Mean = Sum of the product of Number of students and Average marks/Total observation

Calculation:

Number of observation (people) = (3 + 4 + 1 + 1 + 1 + 0) = 10

Sum of the product of Number of students and Average marks

⇒ (3 × 1 + 4 × 3 + 1 × 5 + 1 × 7 + 1 × 9 + 0 × 11)

⇒ (3 + 12 + 5 + 7 + 9)

⇒ 36

According to the question,

Mean = Sum of the product of Number of students and Average marks/Total observation

⇒ Mean = 36/10

∴ Mean marks of Class A = 3.6

GIVEN:

Average of N1 and N2 = 17

Average of N2 and N3 = 44

CONCEPT:

Basic Average concept.

FORMULA:

Average = Sum of numbers/Total Numbers

CALCULATION:

⇒ N1 + N2 = 34     --- (i)

⇒ N2 + N3 = 88     --- (ii)

Subtracting (i) from (ii)

⇒ N2 + N3 - N1 - N2 = 88-34

⇒ N3 - N1 = 54.

∴ the difference between N3 and N1 is 54

Given:

Height of the cone, h = 28 cm

Diameter of the cone, d = 42 cm

Radius of the cone, r = 42/2 = 21 cm

Formula used:

Slant height of the cone, l = √(h² + r²)

Therefore, Curved surface area CSA of the cone = π × r × l

Calculation:

Slant height = √(Radius² + Height²)

⇒ l = √(28² + 21²) = √1225 = 35 cm

Now, CSA of cone = 22/7 × 21 × 35

⇒ 22 × 3 × 35

⇒ 2310 cm²

∴ The curved surface area of the cone is 2310 cm²

Given:

Cost price = Rs. 1240

Loss percentage = 32%

Formula used:

Loss = Cost Price – Selling price

Loss percentage = (Cost Price – Selling price) × 100/Cost Price

Calculation:

⇒ Loss percentage = (1240 – S.P.) × 100/1240

⇒ 32 = (1240 – S.P.) × 100/1240

⇒ 32 = (1240 – S.P.) × 100/1240

⇒ 32 × 1240 = (1240 – S.P.) × 100

⇒ 32 × 1240 = 1240 × 100 – S.P. × 100

⇒ S.P. × 100 = 1240 × 100 – 32 × 1240

⇒ S.P. × 100 = 1240 (100 – 32)

⇒ S.P. = 1240 (68)/100

⇒ S.P. = Rs. 843.2

Given :

Cost Price = Rs. 1240

Loss = 32%

Calculations:

According to the question,

Selling Price = [(100 – 32)/100] × 1240

Selling Price = 1240 (68)/100

Selling Price = Rs. 843.2

Given :

Total rainfall for Town B = 455

Average daily rainfall for first 2 days = 105

Total rainfall for first 2 days = 210

Average daily rainfall for next 3 days = 84

Total rainfall for next 3 days = 252

Average daily rainfall for last 2 days = 49

Total rainfall for last 2 days = 98

Formula used:

Average = Sum of all quantities/Total number of quantities

Calculations :

⇒ Total rainfall for Town A = 210 + 252 + 98 = 560

⇒ Average daily rainfall for Town A and B together = (560 + 455)/7

⇒ Average daily rainfall for Town A and B together = 1015/7

⇒ Average daily rainfall for Town A and B together = 145

∴ the average daily rainfall of both the towns together is 145.

The correct answer is: than beg.

Key Points

• 'rather' and 'beg' are correlative conjunctions.
• Correlative conjunctions are sort of like tag-team conjunctions. They come in pairs, and you have to use both of them in different places in a sentence to make them work. They get their name from the fact that they work together (co-) and relate one sentence element to another.
• For example: I would rather work than sleep.
• Similarly, in the question, 'rather' is present in the sentence. Hence, 'than' must fit the blank. Thus, options 1) and 3) are incorrect.
• Also, the use of the preposition 'to' is superfluous after 'than'. Hence, option (2) is incorrect.

Therefore, the correct answer is: I would rather serve than beg.

Additional Information

• Some of the important Correlative Conjunctions are:
• Either….or
• Neither….nor
• Hardly….when
• Scarcely….when
• Both…and
