The correct answer is- 'error lies in the part-3'

Key Points

• Using 'beside' in the place of 'besides' makes the sentence errorless.
• 'Beside' is a preposition and It means ‘at the side of’ or ‘next to’.
• Example: Your shoes are beside the closet

In solving this eq. 25!/8^7, it is exactly divided by 8^7.

∴ The correct answer is 7.

Alternate MethodCalculation:

Take out the 2’s factor from 25!

⇒ 25/2 = 12

⇒ 12/2 = 6

⇒ 6/2 = 3

⇒ 3/2 = 1

⇒ 1/2 = 0

Now add all the factors of ‘2’ = 12 + 6 + 3 + 1 + 0 = 22

⇒ Factors of 2 in 25! = 2²² = 8⁷ × 2

∴ The correct answer is 7.

Calculation:

157 × 157 + 143 × 143 = (150 + 7)² + (150 – 7)²

⇒ (150)² + (7)² + 2 × 157 × 7 + (150)² + (7)² – 2 × 157 × 7

⇒ 2 × (150)² + 2 × (7)² = 45000 + 98 = 45098

∴ The correct answer is 45098.

Given:

y - (1/y) = 4

Concept used:

If $y - \frac{1}{y} = k$ than

⇒ y³ - (1/y³) = k³ + 3k

Calculation:

⇒ y - (1/y) = 4

Here, k = 4

⇒ y³ – 1/y³

⇒ 4³ + 3 × 4

⇒ 64 + 12 = 76

∴ The correct answer is 76.

Given:

a = √(5 + 2√2); 

b = √(5 – 2√2)

Calculation:

⇒ a² – b² = (√(5 + 2√2))² – (√(5 – 2√2))²

⇒ 5 + 2√2 – 5 + 2√2

⇒ 4√2

∴ The correct answer is 4√2.

Two traingels ABC and PQR are congruence as per SAS when two sides and an angle of both the triangles are same

As per SAS,

 AB = PQ, BC = QR and ∠B = ∠Q

“Circumcenter” is the point at which the perpendicular bisectors of the sides meet and the center of the circle that circumscribes the triangle is “Circumcenter”.

Let the no. is a

60% of a + 60 = a

⇒ 3/5 × a + 60 = a

⇒ a – 3/5 × a = 60

⇒ 2/5 × a = 60

∴ a = 150

Given:

Ratio of salary of u : v : w = 8 : 7 : 13

Calculation:

Salary of u = 8k, v = 7k and w = 13k

Difference of salary of v and w = 3384

⇒ 13k – 7k = 3384

⇒ k = 564

∴ Salary of u = 8k = 8 × 564 = Rs. 4512

Given:

Total mixture = 80 liters

Calculation:

Let the quantity of new mixtures be 'a' liters.

Acid in the mixture = 20% of 80 litre = 16 litres

Water in the mixture = 80 – 16 = 64 litres

In the new mixture, the water is only 40% and acid is 60%

Water in a new mixture = 40% of a litres = 64 litres

⇒ 2/5 × a = 64 litres

⇒ a = 160 liters

Acid in new mixture = 160 – 64 = 96 liters

Acids that should be added = 96 – 16 = 80 liters

∴ The correct answer is 80 liters.

Alternate MethodCalculation:

Now,

⇒ (4 + 1) = 5 units = 80 liters

⇒ 1 unit = 16 liters

⇒ (6 - 1) = 5 units = 16 × 5 = 80 liters

∴ The correct answer is 80 liters.

Calculation:

Cost of 10 shirts on 1^st day = 10 × 150 = Rs.1500

Cost price of a shirt on 2^nd day = 150 – 30 = Rs.120

Number of shirts purchased on 2^nd day = 1800/120 = 15

Total expenditure = 1500 + 1800 = 3300

Total shirts = 10 + 15 = 25

Average cost of a shirt = 3300/25 = Rs.132

∴ The correct answer is Rs.132.

Given:

S.I. = 1380.5

P = 50200

Time = 3 months = 1/4 year

Calculation:

S.I = (P × R × T)/100

⇒ 1380.5 = (50200 × R × 1) / (100 × 4)

∴ R = 11%

Given:

Selling of 120 bottles, 

Profit equal to the cost price of 10 bottles 

Concept used:

C.P = S.P – P

P% = (P/C.P) × 100 

Where, 

C.P → Cost price 

S.P → Selling price 

P →  Profit 

Calculations:

120C.P = 120S.P – 10C.P 

⇒ 130C.P = 120S.P

⇒ C.P/S.P = 120/130 = 12/13

Profit = 13 – 12 = 1 

Profit % = (1/12) × 100 = 8.33%

∴ Profit % is 8.33%

Given:

Marked Price of shirt = Rs.1800

Retailer's S.P = Rs.1800

Calculation:

Retailer's cost Price of shirt = (100 – 40)% of 1800

⇒ 60% of 1800

⇒ 3/5 × 1800 = 1080

Profit % = (S.P. – C.P.) /(C.P.) × 100

⇒ (1800 – 1080) /1080 × 100

⇒ 2/3 × 100 = 66.66%

∴ The correct answer is 66.66%.

Given:

x = 0.139

Calculation:

⇒ √(4x² + 4x + 1) 

⇒ √(2x + 1)² 

⇒ 2x + 1

putting the value of x in the equation:

⇒ 2 × 0.139 + 1 = 1.278

∴ The correct answer is 1.278.

Given:

Rahul can complete a work = 18 days

Sonu can complete the work = 15 days

Formula used:

Efficiency × Time = Total work

Calculation:

Time taken by Rahul to complete the work = 18 days

Time taken by Sonu to complete the work = 15 days

Let the total work = LCM of 18 and 15 = 90 units

Efficiency of Rahul = 90/18 = 5 units/day

Efficiency of Sonu = 90/15 = 6 units/day

Total Efficiency of Rahul and Sonu = 6 + 5 = 11 units/day

Work was completed by them in 5 days = 11 × 5 = 55 units

Remaining work = 90 – 55 = 35 units

Remaining work = 35/90 = 7/18

∴ The correct answer is 7/18.

Given:

The speed of the train = 35 m/s

Length of tunnel = 960 m

Time to cross the tunnel = 40 s

Formula used:

Distance = Relative speed × Time

Calculation:

Distance = Relative speed × Time

⇒ Length of the train + Length of the Tunnel = Speed of train × Time

⇒ Length of train + 960 = 35 × 40

⇒ Length of train = 1400 – 960 = 440 m

∴ The correct answer is 440 m.

Exports in 2012 compared to previous year = 35 – 50 = -15

Exports in 2013 compared to previous year = 60 – 35 = 25

Exports in 2014 compared to previous year = 45 – 60 = -15

Exports in 2015 compared to previous year = 95 – 45 = 50

Exports in 2016 compared to previous year = 85 – 95 = -10

Exports in 2017 compared to previous year = 55 – 85 = -30

So, required answer is 2015

∴ Difference in the exports between 2012 and 2014 = 45 – 35 = 10

∴ The exports in 2014 were lesser than that in 2011 by = (50 – 45)/50 × 100 = 10%

∴ Total exports by the company in last 4 years = 45 + 95 + 85 + 55 = 280 lakh

Given:

Perimeter pf rectangle = 68 cm

Breadth of rectangle = 10 cm

Formula used:

Perimeter of rectangle = 2 × (Length + breadth)

Calculation:

Perimeter of rectangle = 68

⇒ 2 × ( L + 10) = 68

⇒ 2L + 20 = 68

⇒ L = 24

Now,

D² = L² + B²

⇒ D² = 24² + 10²

⇒ D² = 576 + 100

⇒ D² = 676

⇒ D = 26 cm

∴ The correct answer is 26 cm.

Given:

Radius of semi-circle = 14 cm

Formula used:

∴ The correct answer is 5/6.

Given:

∠E = 90° 

Sec D = 17/8

Calculation: 

Sec D = 17/8 = DF/DE

By Pythagoras Theorem:

(DF)² = (DE)² + (EF)²

⇒ (17)² = (8)² + (EF)²

⇒ (EF)² = 289 – 64 = 225

⇒ EF = 15

Cos F = EF/DF = 15/17

∴ The correct answer is 15/17.

In a chemical formula, the Metal ion is at first and non-metal ion at the second position

Metals tend to form a cation, while non-metals tend to form anions.

When a metal reacts with a nonmetal (or a polyatomic ion), usually Ionic compounds are formed.

While writing the formula of ionic compounds, the cation is written first, followed by the anion.

For example- Na⁺Cl^-, MgO, CaBr₂, etc.

• At synapses of the Neuron, the information is transmitted in the chemical form, called as Neurotransmitter.

Key Points

• Synapse:
• It is the junction between 2 neurons.
• There is a very narrow gap of about 20nm between neurons called the synaptic cleft.
• An action potential cannot cross the synaptic cleft, so nerve impulses are carried by chemicals called neurotransmitters.
• The structure of a synapse:
• At the synapse, the presynaptic neuron communicates with the postsynaptic neuron.
• At the end of the presynaptic neuron, there are synaptic knobs.
• Synaptic knobs contain many mitochondria and large amounts of ER to manufacture neurotransmitters.
• There is a tiny gap known as the synaptic cleft
• Functions of a synapse:
• A single impulse is transmitted to a number of different neurons creating simultaneous responses.
• A number of impulses are combined at a synapse allowing stimuli from different receptors to interact for a single response.

CONCEPT:

Work done (W): When a force is applied on a body and there is a displacement of the body in the direction of force then the work is said to be done by the force.

• The SI unit of work is Joule.
• 1 Joule (J) = 1 Nm

Work (W) = Force (F) × Displacement (S)

Power (P): The rate of work done is called power.

• The SI unit of power is the watt (W).

Power (P) = work done (W) / time (t)   

P = W / t = J / s

CALCULATION:

Given that:

Work (W) = 120 Joules

Time (t)  = 3 seconds

The formula of Power,

P = W/t = 120/3 = 40 Watts

Power of Engine = 40 Watts

Quantitatively, the inertia of an object is measured by its mass.

EXPLANATION:

According to Newton’s First Law of Motion-

• "An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force."
• This tendency of objects to resist change in their state of motion is referred to as inertia.
• This tendency depends on the mass of the object; the more massive an object is, the more it’ll have a tendency to resist change in its state of motion.

The correct answer is An anemometer.

Key Points

• Anemometer: It is an instrument used to measure the speed of the wind, which is a common weather station instrument, or to calculate any form of current gas.
• The term is derived from the Greek word anemos meaning wind which was first explained by Leon Battista Alberti who was an Italian artist and architect in the year 1450.
• He used a mechanical anemometer which was placed perpendicular to the wind direction such that the wind velocity as indicated by the angle of inclination of the disc.
• Types of anemometer:
• Cup anemometer: This consists of four hemispherical cups that are mounted on one end of the horizontal arms at equal angles on a vertical shaft.
• Hotwire anemometer: This consists of thin wire which is heated up to a certain temperature slightly more than atmospheric temperature.
• Windmill anemometer: This is a mechanical device similar to the regular windmill used to calculate the velocity of the wind. It consists of the axis of rotation running parallel to the direction of the wind.
• Laser Doppler anemometer: A beam of light is used which is further split into two beams. The velocity is determined by calculating the amount of light that has been reflected.
• Sonic anemometer: Sound waves from this anemometer are used to obtain the speed of the wind. These waves are made to pass through the transducer. These find applications in aircraft and scientific wind turbines.
