⇒ 46 - 320

⇒ -274

Option  3) 32 B 8 D 160 C 2 A 42 ⇒ 32 × 8 – 160 + 2 ÷ 42

⇒ 32 × 8 – 160 + 2 ÷ 42

⇒ 32 × 8 – 160 + 0.04

⇒ 256 +0.04 - 160

⇒ 256.04 - 160

⇒ 196.04

Option  4) 32 C 8 D 160 A 2 B 42 ⇒ 32 + 8 – 160 ÷ 2 × 42

⇒ 32 + 8 – 160 ÷ 2 × 42

Given:

Total votes polled = 8,750

Percentage of invalid votes = 20%

Percentage of votes candidate A gets = 63%

Formula used:

Valid votes = Total votes - Invalid votes

Votes for candidate B = Valid votes - Votes for candidate A

Calculation:

Invalid votes = 20% of 8,750

⇒ Invalid votes = 0.20 × 8,750 = 1,750

Valid votes = 8,750 - 1,750

⇒ Valid votes = 7,000

Votes for candidate A = 63% of 7,000

Given:

A cyclist rides 10 km at an average speed of 15 km/hr and then the next 15 km at an average speed of 10 km/hr.

Formula used:

Average Speed = Total Distance / Total Time

Calculation:

First part:

Distance₁ = 10 km

Speed₁ = 15 km/hr

Time₁ = Distance₁ / Speed₁

⇒ Time₁ = 10 / 15

⇒ Time₁ = 2/3 hr

Second part:

Distance₂ = 15 km

Speed₂ = 10 km/hr

Time₂ = Distance₂ / Speed₂

⇒ Time₂ = 15 / 10

⇒ Time₂ = 1.5 hr

Total Distance = Distance₁ + Distance₂

⇒ Total Distance = 10 + 15

⇒ Total Distance = 25 km

Total Time = Time₁ + Time₂

⇒ Total Time = 2/3 + 1.5

⇒ Total Time = 2/3 + 3/2

⇒ Total Time = 4/6 + 9/6

⇒ Total Time = 13/6 hr

Average Speed = Total Distance / Total Time

⇒ Average Speed = 25 / (13/6)

⇒ Average Speed = 25 × 6/13

⇒ Average Speed = 150/13

⇒ Average Speed ≈ 11.54 km/hr

Given:

The sum of the digits of a two-digit number is 9. If the digits are reversed, then the number is increased by 27.

Formula used:

Let the two-digit number be 10x + y, where x and y are the digits.

x + y = 9

When digits are reversed, the number becomes 10y + x

10y + x = (10x + y) + 27

Calculation:

10y + x = 10x + y + 27

⇒ 10y + x - y - 10x = 27

⇒ 9y - 9x = 27

⇒ y - x = 3

Since x + y = 9, add both the equations,

⇒ y = 6

⇒ x = 3

The number is 10x + y = 10×3 + 6 = 36

∴ The correct answer is option (2).

Given:

The vendor uses weights that are 19% less than true weights and makes a profit of 35% on the selling price.

Step 1: Find the effective weight he is using.

Weight used = 100% - 19% = 81% of the true weight.

Step 2: To find the effective profit due to reduced weight:

Effective increase in price due to reduced weight = (100 / 81) - 1 = (100 - 81) / 81 = 19 / 81 = 0.2346 or 23.46%.

Step 3: Now, calculate the total profit.

Total profit = Profit due to reduced weight + Actual profit

Total profit = 23.46% + 35% + (23.46% × 35%) / 100

Total profit = 23.46 + 35 + (23.46 × 35) / 100

Total profit = 23.46 + 35 + 8.211

Total profit = 66.671%

∴ The net gain percentage is 66.67% (rounded off to 2 decimal places).

Given:

55 workers can finish a work in 16 days.

Time required to finish the same work = 10 days

Formula used:

Work = Number of Workers × Number of Days

Calculation:

Let the number of additional workers required be x.

Total work = 55 × 16

⇒ Total work = 880

New number of workers required to finish the work in 10 days = 880 / 10

⇒ New number of workers required = 88

Additional workers required = 88 - 55

⇒ Additional workers required = 33

∴ The correct answer is option (4).

Given:

Ram spends 30% of his salary on food, 10% on house rent, 7% on entertainment, and 6% on conveyance.

Savings at the end of the month = ₹1,880

Formula used:

Total percentage spent = 30% + 10% + 7% + 6%

Total percentage spent + Savings percentage = 100%

Calculation:

Total percentage spent = 30 + 10 + 7 + 6

⇒ Total percentage spent = 53%

Savings percentage = 100% - 53%

⇒ Savings percentage = 47%

Let the monthly salary be x.

Savings = 47% of x

⇒ 0.47x = 1880

⇒ x = 1880 / 0.47

⇒ x ≈ 4000

∴ The correct answer is option (4).

Given:

The total number of students in different subjects along with the percentage of girls and boys:

Formula used:

Total girls = (Percentage of girls / 100) × Total students in each subject

Percentage of girls in the college = (Total girls / Total students) × 100

Calculation:

Total students = 840 + 220 + 450 + 200 = 1710

Girls in Mathematics = (40/100) × 840 = 336

Girls in Chemistry = (70/100) × 220 = 154

Girls in Physics = (30/100) × 450 = 135

Girls in Biology = (80/100) × 200 = 160

Total girls = 336 + 154 + 135 + 160 = 785

Percentage of girls = (785 / 1710) × 100 ≈ 45.9%

∴ The percentage of girl students in the college is approximately 45.9%.

Shortcut Trick

Ratio of Height to Distance is constant for both objects due to the law of reflection.

Height of Man / Distance of Man = Height of Tower / Distance of Tower

1.5 / 0.5 = Height / 105

3 = Height / 105

Height = 105 × 3 = 315 m

∴ The correct answer is 315 m.

Alternate Method

Given:

Height of man (AB) = 1.5 m

Distance of man from mirror (BM) = 0.5 m

Distance of tower from mirror (MD) = 105 m

Let height of tower (CD) = h m

Formula used: Angle of incidence = Angle of reflection, making ΔABM similar to ΔCDM (AA similarity).

Mirror (M)

A (Man) B 1.5m

C (Tower) D h = ?

0.5m 105m θ θ

Calculations:

In ΔABM and ΔCDM:

∠ABM = ∠CDM = 90° (Vertical objects)

∠AMB = ∠CMD (Laws of reflection: Angle of incidence = Angle of reflection)

⇒ ΔABM ∼ ΔCDM (By AA similarity criterion)

⇒ AB / CD = BM / MD

⇒ 1.5 / h = 0.5 / 105

⇒ h = (1.5 × 105) ÷ 0.5

⇒ h = 3 × 105

⇒ h = 315 m

∴ The correct answer is 315 m.

Additional Information

Law of Reflection

When light reflects off a surface, the angle of incidence is equal to the angle of reflection (θ_i = θ_r).

AA Similarity Criterion

If two angles of one triangle are equal to two angles of another triangle, the triangles are similar and their corresponding sides are proportional.

Given:

The pie chart shows the distribution of overseas tourists across four locations:

• Agra = 15%
• Amritsar = 30%
• Konark = 35%
• Kashi = 20%

Calculation:

The percentage of tourists who went to Agra and Kashi:

⇒ Percentage = Agra + Kashi

⇒ Percentage = 15% + 20%

⇒ Percentage = 35%

∴ 35% of tourists went to Agra and Kashi.

Given:

The family saves ₹8,000 per month.

From the pie chart:

• Angle for savings = 60°
• Angle for food = 120°

Formula used:

The expenditure on different heads is proportional to the angles in the pie chart. Therefore, we can use the ratio of the angles to find the ratio of expenditures.

Calculation:

Let the total monthly income be X.

Savings = (60° / 360°) × X = ₹8,000

⇒ (1/6) × X = ���8,000

⇒ X = ₹8,000 × 6 = ₹48,000 (Total monthly income)

Expenditure on food = (120° / 360°) × ₹48,000

⇒ Expenditure on food = (1/3) × ₹48,000 = ₹16,000

Ratio:

Expenditure on food : Savings = ₹16,000 : ₹8,000 = 2:1

∴ The ratio of expenditure on food to that on savings is 2:1.

Given:

Principal (P) = ₹2,430

Simple Interest (SI) = ₹1,093.50

Time (t) = 3 years

Formula used:

SI = P × r × t / 100

Where, r = rate of interest per annum

Calculations:

1,093.50 = 2,430 × r × 3 / 100

⇒ 1,093.50 = 7,290 × r / 100

⇒ 1,093.50 = 72.90 × r

⇒ r = 1,093.50 / 72.90

⇒ r = 15%

∴ The correct answer is option (4).

Given:

Diameter of the cylindrical cup (d) = 7 cm

Height of tea in the cup (h) = 4 cm

Number of patients = 180

π = 22/7

Formula used:

Volume of a cylinder (V) = πr²h

Where, r = radius of the base of the cylinder

Calculations:

Radius (r) = d/2 = 7/2 = 3.5 cm

Volume of tea for one patient = V = (22/7) × (3.5)² × 4

⇒ V = (22/7) × 12.25 × 4

⇒ V = (22/7) × 49

⇒ V = 154 cm³

Total volume of tea for 180 patients = 154 × 180

⇒ Total volume = 27720 cm³

Since 1 litre = 1000 cm³

Total volume in litres = 27720 / 1000

⇒ Total volume = 27.72 litres

∴ The correct answer is option 4.

Given:

Given:

A cuboidal water purifier can carry 10 litres of water. Its breadth is (1)/(5) of its height and length is (1)/(3) of the sum of the breadth and height.

Formula used:

Volume of cuboid = length × breadth × height

1 litre = 1000 cm³

Calculations:

Volume = 10 litres = 10 × 1000 cm³ = 10000 cm³

Let height = h cm

Breadth = (1/5)h cm

Length = (1/3)(h + (1/5)h) cm

⇒ Length = (1/3)(6h/5) cm

⇒ Length = 2h/5 cm

Volume = length × breadth × height

⇒ 10000 = (2h/5) × (h/5) × h

⇒ 10000 = (2h³)/(25)

⇒ 10000 × 25 = 2h³

⇒ 250000 = 2h³

⇒ h³ = 125000

⇒ h = ∛125000

⇒ h = 50 cm

∴ The correct answer is option 3.

Given:

Income of Company A (2014) = ₹40 crores

Profit percentage = 25%

Formula used:

Profit% = (R - E)/E × 100

Where R = Revenue, E = Expenditure

Calculation:

Profit% = (R - E)/E × 100

⇒ 25 = (40 - E) / E × 100

⇒ E = (40 - E) × 4

⇒ E = 160 - 4E

⇒ 5E = 160

⇒ E = 160 / 5 = 32 crores

∴ The expenditure of Company A in 2014 is ₹32 crores.

Given:

Length of common internal tangent (L) = 6 units

Radius of the first circle (r₁) = 2 units

Radius of the second circle (r₂) = 3 units

Formula used:

For two circles with radii r₁ and r₂, and the length of the common internal tangent L, the distance d between their centers can be given by:

$\sqrt{d^2 - (r_1 + r_2)^2} = L$

Calculation:

$\sqrt{d^2 - (2 + 3)^2} = 6$

⇒ $\sqrt{d^2 - 25} = 6$

⇒ $\sqrt{d^2 - 25} = 6$

⇒ $(d^2 - 25) = 6^2$

⇒ $(d^2 - 25) = 36$

⇒ $d^2 = 36 + 25$

⇒ $d = \sqrt{61}$

∴ The correct answer is option 1.

Given:

If tan A = √2 - 1

Formula used:

tan A = sin A / cos A

sin A cos A = 1/2 sin 2A

Calculation:

If tan A = √2 - 1, then

sin A / cos A = √2 - 1

Let sin A = x and cos A = y, then

x / y = √2 - 1

⇒ x = y(√2 - 1)

⇒ x² + y² = 1

Substitute x = y(√2 - 1)

⇒ (y(√2 - 1))² + y² = 1

⇒ y²(√2 - 1)² + y² = 1

⇒ y²(2 - 2√2 + 1) + y² = 1

⇒ y²(3 - 2√2) + y² = 1

⇒ y²(4 - 2√2) = 1

⇒ y² = 1 / (4 - 2√2)

⇒ y = 1 / √(4 - 2√2)

Now, sin A = y(√2 - 1)

sin A cos A = 1/2 sin 2A

sin 2A = 2 sin A cos A

Substitute sin A and cos A

⇒ sin 2A = 2 × (y(√2 - 1)) × y

⇒ sin 2A = 2 × (√2 - 1) / √(4 - 2√2)

sin A cos A + tan A = sin A cos A + √2 - 1

⇒ sin A cos A + tan A = 1/2 sin 2A + √2 - 1

⇒ sin A cos A + tan A = (√2 - 1) / √(4 - 2√2) + √2 - 1

After solving, we get:

⇒ sin A cos A + tan A = (5√2 - 4) / 4

∴ The correct answer is option 2.

Given:

The person is 30 minutes late when traveling at 3 km/h.

The person is 30 minutes early when traveling at 4 km/h.

Formula used:

Time taken at 3 km/h: T + 1/2 = D / 3

Time taken at 4 km/h: T - 1/2 = D / 4

Calculation:

From equation (1): T = (D / 3) - 1/2

From equation (2): T = (D / 4) + 1/2

Equating both: (D / 3) - 1/2 = (D / 4) + 1/2

⇒ (4D - 3D) / 12 = 1

⇒ D / 12 = 1

⇒ D = 12

∴ The distance to the destination is 12 km.

Given:

Four years ago, Ravi was four times as old as Kavya.

Seven years from now, Ravi will be three times as old as Kavya.

Formula used:

Let Ravi's present age be R years and Kavya's present age be K years.

Four years ago: R - 4 = 4(K - 4)

Seven years from now: R + 7 = 3(K + 7)

Calculations:

R - 4 = 4(K - 4)

⇒ R - 4 = 4K - 16

⇒ R = 4K - 12

R + 7 = 3(K + 7)

⇒ R + 7 = 3K + 21

⇒ R = 3K + 14

Equating the two expressions for R:

4K - 12 = 3K + 14

⇒ 4K - 3K = 14 + 12

⇒ K = 26

Substituting K in R = 4K - 12:

R = 4 × 26 - 12

⇒ R = 104 - 12

⇒ R = 92

Sum of their present ages:

R + K = 92 + 26

⇒ R + K = 118

∴ The correct answer is option 3.
