Calculation:

Let the number be x

According to the question,

⇒ x - 39 = 79 - x

⇒ 2x = 118

⇒ x = 118/2

⇒ x = 59

∴ the number is 59.

Shortcut TrickThe number will be the average of the given numbers.

The number = (39 + 79)/2 = 59

∴ The required number is 59.

Given, (1/3.197) = 0.3127

∴ (1/0.0003197) = (1/3.197) × 10000 = 0.3127 × 10000 = 3127

4x + 3y = 0

When x = 0 then y = 0

When x = -3 then y = 4

And, 7x + 5y = 0

When x = 0 then y = 0

When x = 5 then y = -7

The two lines 4x + 3y = 0 and 7x + 5y = 0 will intersect each other at one point only in their graphical representation.

Alternate MethodGiven equation are 4x + 3y = 0 and 7x + 5y = 0.

a₁/a₂ ≠ b₁/b₂ ⇒ 4/7 ≠ 3/5

In this situation, the equation will have a unique solution. If we remember this, there is no need to sketch any graph.

Concept:

For infinite solutions,

a1/a2 = b1/b2 = c1/c2

Calculation:

Line px + 6y + 3 = 0 when compared with a₁x + b₁y + c₁ = 0

So, a₁ = p, b₁ = 6 and c₁ = 3

Line 2x + qy + 3 = 0 when compared with a₂x + b₂y + c₂ = 0

So, a₂ = 2, b₂ = q and c₂ = 3

⇒ p/2 = 6/q = 3/3

⇒ p/2 = 3/3

⇒ p = 2

And, 6/q = 3/3

⇒ q = 6

So, value of p and q = 2, 6

Equilateral triangle has maximum area when inscribed inside the circle of the same radius

Let the radius of circle AO = BO = CO = 2r and side of triangle is a

In equilateral triangle medians intersect in ratio 2 : 1,

So, OG = AO/2 = 2r/2 = r

⇒ BG² = BO² - OG²

⇒ BG² = (2r)² - (r)²

⇒ BG² = 4r² - r²

⇒ BG² = 3r²

⇒ BG = √3r

⇒ BC = 2 × BG = 2√3r = AB = CA

∴ Area of equilateral triangle ABC = (√3)/4 × (side)² = (√3)/4 × (2√3r)² = (√3)/4 × 12r² = 3√3r²

Concept used:

Each median divides the other median in the ratio of 2 : 1.

Calculation:

According to the theorem,

Each median divides the other median in the ratio of 2 : 1.

∴ Option 3 is the correct answer.

Calculation:

Let B = 100

So, A = (100 + 40)% of B = 140% of 100 = 140

∴ Required % = (140 - 100)/140 × 100 = 2/7 × 100 = 28.57%

Alternate MethodA = 140% of B

⇒ A/B = 7/5

The difference = 7 - 5 = 2 units.

The percentage difference = 2/7 × 100 = 28.57%

Given:

(4/5)A = 3B = (2/3)C

Calculation:

(4/5)A = 3B = (2/3)C = K(Let)

⇒ A = 5K/4, B = K/3, C = 3K/2

⇒ Ratio = 5K/4 ∶ K/3 ∶ 3K/2

⇒ 12 × 5K/4 ∶ 12 × K/3 ∶ 12 × 3K/2

⇒ 15 ∶ 4 ∶ 18

Given:

A mixture contains 7% alcohol

Calculation:

Alcohol = 7% = 357 litres

⇒ 1% = 357/7 =  51 litres

Total mixture = 100% = 5100 litres.

∴ The correct answer is 5100

∴ Average = (36 + 43 + 51 + 68 + 77)/5 = 275/5 = 55

Alternate MethodDeflection method:

Let the average be 51.

The total deflection = (51 - 36) + (51 - 43) + (51 - 51) + (51 - 68) + (51 - 77)

⇒ 15 + 8 + 0 - 17 - 26

⇒ -20

Correct average = 51 + 20/5 = 55

Concept used:

• Simple interest = (P × T × R)/100, where P = principal, T = time, R = rate

• Amount = Simple interest + Principal

Calculation:

According to the question,

S.I. = Amount - Principal = 77P/50 - P = 27P/50

⇒ 27P/50 = (P × R × 18)/(100 × 5)

∴ R = 30/2 = 15%

Given:

The ratio of Cost price and Selling price is 15 : 18

Concept used:

• Profit% = (S.P - C.P)/C.P × 100

Calculation:

According to the question,

C.P = 15 unit and S.P = 18 unit

Profit % = (18 - 15)/15 × 100 = 20%

∴ The correct answer is 20%

Scheme I. Two successive discounts of 20% and 25%

So, effective discount for scheme I is = 20 + 25 - (20 × 25)/100 = 45 - 5 = 40%

Scheme II. Buy 5 get 3 free

So, effective discount for scheme II is = (Article get free)/(Total articles) × 100 = 3/(5 + 3) × 100 = 37.5%

Scheme III. Buy 5 get 6

So, effective discount for scheme III is = (Article get free)/(Total articles) × 100 = 1/(6 ) × 100 = 16.67%

So, answer is Scheme I.

Calculation:

${9^x} = \sqrt[{11}]{{243}}$

⇒ (3)^22x = (3)⁵

⇒ x = 5/22

∴ The value of x = 5/22

Concept used:

Total work = Efficiency × Time

Calculation:

Time taken by M to complete 3/4 part of a work = 12 days

Time taken by M to complete whole work = 12 × 4/3 = 16 days

Time taken by N to complete 2/7 part of a work = 8 days

Time taken by N to complete whole work = 8 × 7/2 = 28 days

Total work = LCM of 16, 28 = 112 units

Efficiency of M = 112/16 = 7 units/day

Efficiency of N = 112/28 = 4 units/day

Efficiency of M and N together = 7 + 4 = 11 units/day

∴ Time taken by M and N together to complete 11/14 part of work = 11/14 × 112 × 1/11 = 8 days

Given:

The train travels from a place X at 7:00 a.m to place Y at 1:00 p.m,

Speed of the train = 15 m/s

Concept used:

Speed = Distance/Time

Calculation:

Time taken by train = 6 hours

Speed of train = 15 m/s = 15 × 18/5 = 54 km/hr

Speed of train = Distance/Time

⇒ 54 = Distance/6

∴ Distance = 54 × 6 = 324 km

∴ As shown in the , the value of A is 180 which is highest. So answer = A.

Total No. of employees = Employees in (A + B + C + D + E + F + G)

Total expenditure = 180 + 20 + 20 + 160 + 20 + 80 + 120

∴ Total expenditure = 600

∴ The central angle of the sector representing F is = 80/600 × 360 = 48°

Calculation:

Average salary of employees = 6000 $

Total no. of employees = 600

∴ Total of the salary paid (million $) = 600 × 6000/1000000 = 36/10 = 3.6 million$

Given:

Area = 54 cm², the two parallel sides of a trapezium are 8 cm and 10 cm 

Concept used:

Area = 1/2 × (sum of parallel sides) × (Distance between parallel sides)

Calculation:

According to the question,

⇒ 54 = 1/2 × (8 + 10) × (Distance between parallel sides)

∴ Distance between parallel sides = 54/9 = 6 cm

Given:

The circumference of a circle is 22 cm

Concept used:

• Circumference of circle = 2πr

• Area of circle = πr²

Where r = radius and π = 22/7

Calculation:

Circumference of circle = 2πr = 2 × 22/7 × r = 22

⇒ r = 3.5 cm

∴ Area of circle = πr² = 22/7 × 3.5 × 3.5 = 38.5 cm²

Given:

Total surface area of cube = 337.5 cm²

Formula used:

The total surface area of the cube = 6a2

Calculation:

Explanation:

• Valance Electrons: A valence electron is simply the total number of electrons present in the outermost shell of an atom.
• Valency: Valency is the number of electrons an atom loses, gains or shares with other atoms in order to get a stable configuration.

For example-

Atomic Configuration of Carbon (C ) is ( 6 ) = 2,4

• The valency of Carbon will be 4 as it needs 4 more electrons to get a stable configuration.
• The number of valence electrons in carbon is also four as its outermost shell contains 4 electrons.

Atomic Configuration of Nitrogen N ( 7 ) = 2,5

The valency of nitrogen is 3 as it needs 3 more electrons to complete its octet but the number of valence electrons in nitrogen is 5.

So, 

It can be losing, gaining or sharing of electrons.

Saturated fats are simply fat molecules that have no double bonds between carbon molecules because they are saturated with hydrogen molecules. Saturated fats are typically solid at room temperature. Some food items that contain saturated fats are fatty beef, pork, lamb etc.

The gravitational potential energy of an object is the 'stored energy' that the object has by being at that height. This is equivalent to its mass times the force of gravity, ‘g’ times the height of the object. This means following is the formula:

Potential energy = mass × gravity × height.

Potential Energy = 25 × 10 × 5 = 1250 J

Concept-

Acceleration due to Gravity:

• The force of attraction exerted by the earth on a body is called gravitational pull or gravity. We know that when a force acts on a body, it produces acceleration. Therefore, a body under the effect of gravitational pull must accelerate.

Acceleration due to gravity at the surface of the earth is –

$g = \frac{{GM}}{{{R^2}}}$

Explanation –

As we know that acceleration due to gravity at the surface of the earth is

$g = \frac{{GM}}{{{R^2}}}$

Given - M₁ = M and R₁ = 2R

$\therefore ;g' = \frac{{GM}}{{{{\left( {2R} \right)}^2}}} = \frac{{GM}}{{4{R^2}}} = \frac{g}{4}$

An earthquake is the shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in size and are measured in Richter Scale.
