Key Points

• A radioallergosorbent test (RAST) is a blood test using a radioimmunoassay test to detect specific IgE antibodies, to determine the substances a subject is allergic to.
• ELISA (enzyme-linked immunosorbent assay) is a plate-based assay technique designed for detecting and quantifying substances such as peptides, proteins, antibodies, and hormones. Other names, such as enzyme immunoassay (EIA), are also used to describe the same technology.
• Immunoglobulin E (IgE) are antibodies produced by the immune system. If you have an allergy, your immune system overreacts to an allergen by producing antibodies called Immunoglobulin E (IgE).
• The Hemoglobin A1C test is a blood test that provides information about a person's average levels of blood glucose, also called blood sugar, over the past 3 months. The A1Ctest is based on the attachment of glucose to hemoglobin, the protein in red blood cells that carries oxygen.

Let the number be x

According to the question

⇒ 60 – 6x = 6

⇒ 6x = 60 – 6

⇒ 6x = 54

⇒ x = 54/6

⇒ x = 9

The required number is 9.

Let the breadth of the rectangle be x m

Length of the rectangle = x × 112/100 = 1.12x

According to the question

Area of rectangle = length × breadth

⇒ x × 1.12x = 448

⇒ x² = 448/1.12

⇒ x² = 400

⇒ x = √400

⇒ x = 20

The breadth of the rectangle is 20 m.

The correct answer is Total Internal Reflection,

Explanation:

• The mirage is caused by the total internal reflection of light at layers of air of different densities.

• In a desert, the sand is very hot during day time and a result the layer of air in contact with it gets heated up and becomes lighter. The lighter air rises up and the denser air from above comes down.

• As a result, the successive upper layers are denser than those below them. A ray of light coming from a distant object, like the top a tree, gets refracted from a denser to a rarer medium.

• Consequently, the refracted ray bends away from the normal until, at a particular layer, the light is incident at an angle greater than the critical angle.

• At this stage, the incident ray suffers total internal reflection and is reflected upwards.

• When this reflected beam of light enters the eyes of the observer, it appears as if an inverted image of the tree is seen and the sand looks like a pool of water.

So, Mirage is an example of total internal reflection which occurs due to atmospheric refraction.

The relation is:

Resolution - a firm decision to do or not to do something; the quality of being determined or resolute.

Determination - having made a firm decision and being resolved not to change it.

Resolution : Determination → They are synonyms of each other.

Similarly,

Consensus – a general agreement.

A. Difference - a point or way in which people or things are dissimilar.

B. Unanimity - agreement by all people involved; consensus.

C. Decide - come or bring to a resolution in the mind as a result of consideration.

D. Outcome - the way a thing turns out; a consequence.

Consensus and Unanimity are synonyms of each other.

Hence, ‘unanimity’ is the correct answer.

Total number people preferred train = 145 + 110 + 155 = 410

Total number people preferred bus = 100 + 100 + 100 = 300

Total number people preferred cycle = 150 + 115 + 150 = 415

Total number people preferred taxi = 155 + 100 + 150 = 405

Cycle is the most preferred mode of transport.

Number of people wanting to travel by train and bus = 145 + 110 + 155 + 100 + 100 + 100 = 710

Solution: Number of people wanting to travel by Taxi and own car = 155 + 100 + 150 + 125 + 175 + 100 = 805

Required difference = 805 – 710 = 95

Total number of persons who prefer taxi = 155 + 100 + 150 = 405

Total number of persons who prefer own car = 125 + 175 + 100 = 400

Required difference = 405 – 400 = 5

Assertion (A): Tungsten filament is used for making light bulbs. → True

Reason (R): Tungsten has a high melting point. → True

Tungsten is used as the filament in incandescent light bulbs because it has the highest melting point of any metal (greater than 3400 deg. Celsius) and the higher the temperature, the greater the efficiency and whiter the light.

 Hence, both A and R are true and R is the correct explanation of A.

Share ratio of K, L and M = 2/3 : 3/4 : 1/2 = 24/3 : 36/4 : 12/2 = 8 : 9 : 6

⇒ 8 + 9 + 6 = 23 unit

⇒ 23 unit = 3105/23

⇒ 1 unit = 3105/23 = 135

⇒ 9 unit = 135 × 9 = 1215

Profit share of L is Rs. 1215

According to given Information:

Hence, ‘bd’ is the code of ‘you’.

As we know,

⇒ (a - b)² = a² + b² - 2ab

⇒ ab = 72/2

⇒ ab = 36

The logic is:

Similarly,

Hence, ‘52’ is the correct answer.

Total money at the end of the year invested by N = 12 × 20,000 = 2,40,000

Total money at the end of the year invested by C = 6 × 10,000 = 60,000

Ratio of profit share N to C = 2,40,000 : 60,000 = 4 : 1

Ratio of profit share N to C = 4x : x

⇒ 4x + x = 10,000

⇒ 5x = 10,000

⇒ x = 10,000/5

⇒ x = 2,000

Profit share of N = 4 × 2 = 8

The code for each letter is shown below:

T is coded as either ‘1’ or ‘4’.

In a farm, there are goats and peacocks.

If the number of heads are 60.

G + P = 60

= > P = 60 - G     ---(i)

The number of feet are 170

4G + 2P = 170      ---(ii)

Substituting the value of equation (i) in (ii), we get:

4G + 2(60 – G) = 170

= > 4G + 120 – 2G = 170

= > 2G = 170 – 120

= > 2G = 50

= > G = 25

Hence, the number of goats is 25.

As we know,

Average speed = total distance/total time

Total distance = 40 + 30 = 70 km

SI = Prt/100

Calculation:

When the interest increased, an extra Rs 120 was added to the interest.

That is, the 2% increase in interest = Rs 120

⇒ 120 = (P × 2 × 1) /100

⇒ P = 12000/2

⇒ P = 6000

The sum is Rs. 6000.

∴ The principal is Rs 6000.

Let the radius of the circle be r cm

Circumference of the circle = 2πr

New radius of the circle = (r + x)

New circumference of the circle = 2π (r + x) = 2πr + 2πx

Circum increased by = 2πr + 2πx – 2πr = 2πx

The International Space Station is a space station, or a habitable artificial satellite, in low Earth orbit. Its first component launched into orbit in 1998, and the ISS is now the largest man-made body in low Earth orbit and can often be seen with the naked eye from Earth.

The correct answer is the Plane mirror.

Key Points

• Periscope consists of an outer case with plane mirrors at each end set parallel to each other at a 45° angle.
• A periscope is an optical instrument that uses a system of prisms, lenses, or mirrors to reflect images through a tube.
• Light from a distant object strikes the top mirror and is then reflected at an angle of 90 degrees down the periscope tube
• A periscope lets you look around walls, corners, or other obstacles. Submarines have periscopes so that people inside can what is on the surface of the water.

Additional Information

Concept:

• Periscope: It is an optical instrument, uses mirrors at a 45° angle to observe over, around, and through which is prevented by the line of sight.
• It works based on the laws of reflection of light.
• It is used in submarines to view the upper surface sight, hiding positions for military, nuclear reactor, and many other ways

Explanation:

The correct answer is option 3 i.e Periscope

• Periscope is the instrument used in submarines to view objects above sea level.
• Hypsometer is used to measure elevation or height.
• Ondometer is used for measuring the wavelengths of radio waves.
• Pyrheliometer is used for measuring direct beam solar irradiance.

The search team believes that the plane debris recovered in 2016, near Mozambique was highly likely to be from MH370- Malaysian aircraft which disappeared after take-off in 2014.

Conclusions:

I. The debris found near Mozambique definitely belonged to MH370 aircraft. → False

The search team believes, but nothing is proven yet, so the above conclusion cannot be true.

II. The search team is mistaken about the findings. → False

It cannot be concluded that the belief of the team is true or not, so the above conclusion cannot be true.

Hence, neither I nor II follows.

Alluvial soil is a fine-grained fertile soil deposited by water flowing over flood plains or in river beds. It is formed by accumulated sediments transferred by the rivers and rapids, thus, it is amongst the most fertile soils. It is formed by the deposition brought by the rivers. This soil is very fertile and suitable for agriculture.

The family tree diagram is shown below:

Hence, E is grandson of F.

The logic is:

Similarly,

Hence, ‘PELTA’ is the correct answer.

sinθ = 15/17

Perpendicular = P, Hypotenuse = H and Base = B.

sin θ = P/H = 15/17

P = 15 and H = 17

As we know,

H² = P² + B²

⇒ 17² = 15² + B²

⇒ B² = 289 – 225 = 64

⇒ B = √64

⇒ B = 8

⇒ cot θ = B/P

∴ cot θ = 8/15

Let the first number is be x

The second number = 3x

Third number is = 6x

According to the question

⇒ x + 3x + 6x = 70 × 3

⇒ 10x = 210

⇒ x = 21

Smaller number is 21.

The time gap between the last day of the previous session and the first day of the next session should not be more than six months. In practice, however, normally three sessions are held every year.

Given expression: 6 C 78 B 3 A 4 E 6 = ?

After replacing the letters by their meaning, we get:

L.H.S = 6 + 78 ÷ 3 - 4 × 6

= 6 + 26 – 24

= 32 – 24

= 8

Hence, ‘8’ is the correct answer.

The distance from Earth to the sun is called an astronomical unit, or AU, which is used to measure distances throughout the solar system. The AU has been defined as 149,597,870,700 meters (92,955,807 miles).

All prices are quoted in dollar terms and the local currency is no longer used in transactions. Reserve bank of India (RBI) wishes to fix an exact par value for the rupee. Most exchange rates change slightly on a day-to-day basis, and market forces generally determine the basic trends.

The age difference between M and R is the same as that between P and M. M is elder to P but younger to R.

R > M > P

R – M = M – P

= > 2M = R + P       ---(i)

If the sum of the ages of R and P is 66.

R + P = 66      ---(ii)

Substituting the value of equation (ii) in (i), we get:

2M = 66

= > M = 33

Hence, M is 33 years old.

The meaningful word formed by the jumbled letters are:

A. OLEMN → LEMON

B. PEALP → APPLE

C. OGREAN → ORANGE

D. OTTOPA → POTATO

All words except ‘OTTOPA’ are name of fruits, while ‘OTTOPA’ is a vegetable.

Hence, ‘OTTOPA’ is the odd one out.

Total distance = 30 km

3/5 of the total distance = 30 × 3/5 = 18 km

Remaining distance = 30 – 18 = 12 km

Time to cover 18 km distance with 6 km/hr = 18/6 = 3 hr

After reducing the speed by 2 km/hr, the New speed = 6 - 2 = 4 km/hr

Time to cover 12 km distance with 4 km/hr = 12/4 = 3 hr

Total time = 3 + 3 = 6 hrs

Required time = 6 : 30 + 6 hr = 12:30 pm
