If you buy a scooter for Rs. 60,000 and sell it with 10 percent loss, then what will be its selling price?

  1. ((a))

    Rs. 50,000

  2. ((b))

    Rs. 54,000

  3. ((c))

    Rs. 55,000

  4. ((d))

    Rs. 70,000

Show Answer
Answer: ((b))

Rs. 54,000

Shortcut Trick

Loss is 10%, which means the Selling Price is 90% of the Cost Price.

Cost Price = 100% = Rs. 60,000.

10% of Cost Price = Rs. 6,000.

⇒ Selling Price = 90% = 60,000 − 6,000 = Rs. 54,000.

∴ The correct answer is Rs. 54,000.

Alternate Method

Given:

Cost Price (CP) of the scooter = Rs. 60,000

Loss percentage = 10%

Formula Used:

Selling Price (SP) = CP × (100 − Loss%) ÷ 100

Cost Price Rs. 60,000

− 10% Loss (− Rs. 6,000)

Selling Price Rs. 54,000

Calculations:

⇒ SP = 60000 × (100 − 10) ÷ 100

⇒ SP = 60000 × 90 ÷ 100

⇒ SP = 600 × 90

⇒ SP = 54000

∴ The correct answer is Rs. 54,000.

Additional Information

Selling Price with Profit

When an item is sold at a profit, the selling price is directly calculated as: SP = CP × (100 + Profit%) ÷ 100.

Marked Price and Discount

Discount is always provided on the Marked Price (MP), not the Cost Price. The effective selling price becomes SP = MP − Discount.

Successive Discounts

When two continuous discounts of x% and y% are applied, the overall equivalent discount percentage is given by (x + y − x × y ÷ 100)%.

If H = 16, K = 22 and GO = 44, then the value of COME is 

  1. ((a))

    36

  2. ((b))

    72

  3. ((c))

    78

  4. ((d))

    64

Show Answer
Answer: ((b))

72

Here we use the table given below:

Logic:

Letter = (Positional value × 2) = Coded number.

Then,

H = (8 × 2) = 16

And,

K = (11 × 2) = 22

And,

GO = {(7 × 2) + (15 × 2)} = 14 + 30 = 44

Similarly,

COME = {(3 × 2) + (15 × 2) + (13 × 2) + (5 × 2)} = 6 + 30 + 26 + 10 = 72

Hence, the correct answer is "Option (2)".

  1. ((a))

    12

  2. ((b))

    14

  3. ((c))

    17

  4. ((d))

    21

Show Answer
Answer: ((c))

17

Logic:

Third number = {First number + second number + (First number - 2)}

In 3 + 4 = 8 →

⇒ {3 + 4 + (3 - 2)}

⇒ {3 + 4 + 1} = 8

In 4 + 5 = 11 →

⇒ {4 + 5 + (4 - 2)}

⇒ {4 + 5 + 2} = 11

In 5 + 6 = 14 →

⇒ {5 + 6 + (5 - 2)}

⇒ {5 + 6 + 3} = 14

Similarly,

In 6 + 7 = 17 →

⇒ {6 + 7 + (6 - 2)}

⇒ {6 + 7 + 4} = 17

Hence, the correct answer is "17".

A meter is a measurement of an object's

  1. ((a))

    weight

  2. ((b))

    length

  3. ((c))

    mass

  4. ((d))

    speed

Show Answer
Answer: ((b))

length

The Correct Answer is: Length

Key Points

  • A “meter” is the base unit of length or distance. It is used to measure length and distances just like feet, miles or kilometers.

Additional Information

  • Mass is a fundamental characteristic property of matter. It exists independently and is autonomous of every other boundary, such as the temperature, pressure, and the area of the object in space
  • Mass of an object is measured by the SI Unit of mass that is the kilogram (kg)
  • While the mass is the characteristic property of the body, weight is the proportion of the power applied to the mass of the body because of gravity
  • Mass of any given object is the total matter in it at that point in time whereas the weight of an object is the total force acting upon the object.
  • On the other hand, weight is the force exerted on an object due to gravity and it changes from place to place if the gravitational force changes
  • The gravitational force exerted on an object is directly proportional to the mass of the object which means, when the mass of the object is heavy, it exerts more gravitational force and when the mass of the object is less, it exerts comparatively lesser gravitational force
  • Basically, in physics, speed is the rate of covering of distance. In other words, speed can be defined as the distance which a moving body is covering in a unit time of the motion occurring.
  • Notice that speed is defined as the distance covered per unit of time and not as the displacement happened per unit of time.

Which one of the following is correct measurement from smallest to largest?

  1. ((a))

    Bytes, megabytes, kilobytes, gigabytes

  2. ((b))

    Megabytes, bytes, gigabytes, kilobytes

  3. ((c))

    Bytes, kilobytes, megabytes, gigabytes

  4. ((d))

    Bytes, megabytes, gigabytes, kilobytes

Show Answer
Answer: ((c))

Bytes, kilobytes, megabytes, gigabytes

The Correct Answer is:Bytes, kilobytes, megabytes, gigabytes

Key Points

  • Bytes, kilobytes, megabytes, and gigabytes are units of digital information storage capacity
  • A byte is the smallest unit of digital information and is equivalent to 8 bits.
  • A bit is a basic unit of information in computing that represents a value of either 0 or 1.
  • A kilobyte (KB) is equal to 1,024 bytes. It is often used to measure the size of small files like text documents, images, and simple programs.
  • A megabyte (MB) is equal to 1,024 kilobytes, or 1,048,576 bytes. It is often used to measure the size of larger files like music files, photos, and videos.
  • A gigabyte (GB) is equal to 1,024 megabytes, or 1,073,741,824 bytes. It is often used to measure the size of even larger files like high-definition videos, large software applications, and other large multimedia files.
  • In summary, as you move up the hierarchy from bytes to kilobytes, megabytes, and gigabytes, the unit of measurement increases exponentially, representing an increasing amount of storage capacity.

Show Answer
Answer: ((c))

30.1

Given:

Total number of students = 100

Average marks = 30

Formula Used:

Average = Sum of numbers / total numbers

Calculation:

Now, the Sum = 100 × 30 = 3000

Given, Later on it was found that the marks 30 of one student were misread as 20.

Actual Sum = 3000 - 20 + 30 = 3010

Correct Average = 3010100\frac{3010}{100} = 30.1

∴ The correct average is 30.1.

The average rainfall at a certain place from Monday to Saturday is 3.5 cm. Due to heavy rain on Sunday, the average for the whole week increases to 5 cm. What was the rainfall on Sunday?

  1. ((a))

    10 cm 

  2. ((b))

    27.5 cm

  3. ((c))

    30 cm 

  4. ((d))

    14 cm

Show Answer
Answer: ((d))

14 cm

Shortcut Trick

Average for 6 days (Mon−Sat) = 3.5 cm

Average for 7 days (Mon−Sun) = 5 cm

Rainfall on Sunday = New Average + [Days × Increase in Average]

⇒ 5 + [6 × (5 − 3.5)] = 5 + [6 × 1.5] = 5 + 9 = 14 cm

∴ The correct answer is 14 cm.

Alternate Method

Given:

Average rainfall (Mon to Sat) = 3.5 cm

Average rainfall (Mon to Sun) = 5 cm

Formula Used:

Total = Average × Number of observations

Calculations:

⇒ Total rainfall from Monday to Saturday = 6 × 3.5 = 21 cm

⇒ Total rainfall from Monday to Sunday = 7 × 5 = 35 cm

⇒ Rainfall on Sunday = Total (7 days) − Total (6 days)

⇒ Rainfall on Sunday = 35 − 21 = 14 cm

∴ The correct answer is 14 cm.

Additional Information

Weighted Average

When two groups are combined, the new average is (n1x1 + n2x2) ÷ (n1 + n2).

Net Deviation Method

The sum of deviations of all observations from the average is always zero. This is useful for finding a missing value.

Average Change

If each observation is increased by 'k', the average also increases by 'k'.

Solve brackets and 'of' directly using mental BODMAS:

⇒ (6/10 × 5/4) = 3/4

⇒ (3/4 ÷ 4/6) = (3/4 × 6/4) = 9/8

⇒ 1/2 of 3/4 = 3/8

⇒ 1/4 + 3/4 − 9/8 + 3/8 = 1 − 6/8 = 1 − 3/4 = 1/4

∴ The correct answer is 1/4.

Alternate Method

Given:

1/4 + (6/10 × 5/4) − (3/4 ÷ 4/6) + 1/2 of 3/4

Method Used:

Apply BODMAS rule: Brackets, Of, Division, Multiplication, Addition, Subtraction.

Calculations:

⇒ Step 1: Solve the 'Of' part

⇒ 1/2 of 3/4 = 1/2 × 3/4 = 3/8

⇒ Step 2: Solve the brackets

⇒ First bracket: 6/10 × 5/4 = 30/40 = 3/4

⇒ Second bracket: 3/4 ÷ 4/6 = 3/4 × 6/4 = 18/16 = 9/8

⇒ Step 3: Substitute the simplified values back into the expression

⇒ 1/4 + 3/4 − 9/8 + 3/8

⇒ Step 4: Take the LCM of the denominators (4 and 8), which is 8

⇒ (2/8) + (6/8) − (9/8) + (3/8)

⇒ (2 + 6 − 9 + 3) / 8

⇒ (11 − 9) / 8

⇒ 2/8 = 1/4

∴ The correct answer is 1/4.

Additional Information

BODMAS Rule

It dictates the exact order of operations: Brackets first, then Of (multiplication), Division, Multiplication, Addition, and finally Subtraction.

Fraction Division

Dividing by a fraction is the same as multiplying by its reciprocal. Rule: a/b ÷ c/d = a/b × d/c.

  • This is a tool for enforcing constitutional discipline over administrative agencies while exercising their powers.

  • It prevents the tyranny of executives.
  • Problems with Judicial Review:
  • Constitutional Provisions for Judicial Review
  • It limits the functioning of the government.
  • It violates the limit of power set to be exercised by the constitution when it overrides any existing law.
  • In India, a separation of functions rather than of powers is followed.
  • The concept of separation of powers is not adhered to strictly. However, a system of checks and balances has been put in place in such a manner that the judiciary has the power to strike down any unconstitutional laws passed by the legislature.
  • The judicial opinions of the judges once taken for any case become the standard for ruling other cases.
  • Judicial review can harm the public at large as the judgment may be influenced by personal or selfish motives.
  • Repeated interventions of courts can diminish the faith of the people in the integrity, quality, and efficiency of the government.
  • There is no direct and express provision in the constitution empowering the courts to invalidate laws,
  • but the constitution has imposed definite limitations upon each of the organs, the transgression of which would make the law void.
  • The court is entrusted with the task of deciding whether any of the constitutional limitations has been transgressed or not.

Additional Information

  • The term 'Judicial Review' is nowhere found written in the Constitution, but the provisions of several Articles (eg. Articles 13, 32, 131, 132, 133, etc.) explicitly confer the power of judicial review on the Supreme Court and the High Courts.
  • The former Supreme Court judge Justice Syed Shah Mohamed Quadri classified the judicial review into the following three categories 
  • Judicial review of constitutional amendments.
  • Judicial review of legislation of the Parliament and State Legislatures and subordinate legislations.
  • Judicial review of administrative action of the Union and State and authorities under the state

Proteins after digestion are converted into

  1. ((a))

    carbohydrates

  2. ((b))

    small globules

  3. ((c))

    amino acids

  4. ((d))

    starch

Show Answer
Answer: ((c))

amino acids

The correct answer is amino acids.

Key Points 

  • When protein reaches our stomach, hydrochloric acid and enzymes called proteases (also called peptidase or proteinase) break it down into smaller chains of amino acids.
  • From our stomach, these smaller chains of amino acids move into the small intestine.
  • As this happens, the pancreas releases enzymes and a bicarbonate buffer that reduces the acidity of digested food.
  • This reduction allows more enzymes to work on further breaking down amino acid chains into individual amino acids.

Additional Information 

  • Carbohydrates - It is digested by amylase, converted into glucose, and is finally converted into glycogen for storage.
  • Starch - It is a special type of carbohydrate and is digested in a similar manner.
  • Small globules - It is basically small drop or ball of a liquid floating in a medium.
  • A protease (also called a peptidase or proteinase) is an enzyme that catalyzes (increases reaction rate or "speeds up") proteolysis, breaking down proteins into smaller polypeptides or single amino acids, and spurring the formation of new protein products.

  3. ((c))

    blood

  4. ((d))

    haemoglobin

Show Answer
Answer: ((d))

haemoglobin

The correct answer is Haemoglobin.

Key Points 

  • The Hemoglobin molecules with the help of external chemical factors take up oxygen molecules in the lungs and then send them to the various tissues of our body.
  • Iron is the main constituent of hemoglobin.
  • The normal level of hemoglobin is 13 to 17 grams per deciliter in men and 12.0 to 15.5 grams per deciliter in women.

Important Points 

  • Melanin is a dark biological pigment found in skin, hair, feathers, scales, eyes, and some internal membranes.
  • Rhodopsin is called visual purple, a pigment-containing sensory protein that converts light into an electrical signal.
  • Bilirubin is a yellowish substance in your blood. It forms after red blood cells break down, and it travels through your liver, gallbladder, and digestive tract before being excreted.

Additional Information 

  • The biggest regulator of oxygen affinity in Hemoglobin is the oxygen itself.
  • If in the lungs, the oxygen levels are high the Hemoglobin shows a greater affinity towards the oxygen molecules, and as it bounds to more oxygen, this property of affinity increases and vice versa.
  • When the Oxyhemoglobin binds to the maximum capacity, it becomes saturated but its affinity towards oxygen increases whereas when this binding loose oxygen molecule the affinity decreases.
  • This regulation activity is called Cooperativity and is an important function as it allows the maximum amount of Hemoglobin to be carried to the tissues and also allows deoxyhemoglobin which is releasing the oxygen tissue.

Malaria causing microbes go to which one of the following organs?

  1. ((a))

    Lung

  2. ((b))

    Liver

  3. ((c))

    Brain

  4. ((d))

    Kidney

Show Answer

Liver

The Correct Answer is:Liver

Key Points

  • Malaria-causing microbes, which are typically Plasmodium species such as Plasmodium falciparum, Plasmodium vivax, Plasmodium malariae, and Plasmodium ovale, infect and replicate within red blood cells.
  • During their life cycle, the Plasmodium parasites initially infect liver cells and reproduce within them before moving to the bloodstream and infecting red blood cells.
  • Once inside red blood cells, the parasites undergo several stages of development, which ultimately lead to the destruction of the infected red blood cells and the release of new Plasmodium parasites that can infect additional red blood cells.
  • As a result of the destruction of infected red blood cells and the resulting immune response, malaria can affect multiple organs in the body, including the liver, spleen, kidneys, and brain. In severe cases, the disease can lead to cerebral malaria, which can cause coma and death

The Correct Answer is:cholera

Key Points

  • Cholera is typically spread through contaminated water and food. The causative agent of cholera is the bacterium Vibrio cholerae, which can survive in saltwater and freshwater environments.
  • The most common way of contracting cholera is by drinking water or eating food that has been contaminated with the feces of an infected person. This can happen when sanitation is poor and human waste is not disposed of safely or when water sources are not properly treated.
  • Cholera can also spread from person to person through the fecal-oral route, which occurs when a healthy person comes into contact with the feces of an infected person. This can happen when people do not wash their hands after using the toilet or when infected individuals handle food that is then consumed by others.

Additional Information

  • The common cold is caused by a viral infection, most commonly by rhinoviruses, coronaviruses, and adenoviruses. It is primarily spread through respiratory secretions, such as when an infected person talks, coughs, or sneezes.
  • Pneumonia is caused by a bacterial, viral, or fungal infection that inflames and fills the air sacs in one or both lungs with fluid or pus.
  • It is spread through respiratory secretions, such as coughing or sneezing, or by touching surfaces contaminated with these secretions and then touching one's face or mouth.
  • Tuberculosis is caused by the bacterium Mycobacterium tuberculosis. It spreads through the air when an infected person coughs or sneezes, releasing droplets containing the bacteria. People can become infected when they inhale these droplets. It can also spread through contact with contaminated surfaces or materials

The correct answer is Growth of yeast cells.

Key Points 

  • Bread is made from grain usually wheat.
  • The selected strain of yeast (Saccharomyces cerevisiae) grown on molasses are used as Baker’s yeast.
  • Yeast is added to wheat flour. And is kneaded.
  • The kneaded flour is kept at a warm temperature until it swells up.
  • The phenomenon is called leavening.
  • The process of leavening is done by secretion of 3 enzymes by yeast-
  • Amylase causes a breakdown.
  • Maltase convert maltose into glucose.
  • Glucose is acted upon by zymase.
  • Zymase is a complex of several enzymes of anaerobic respiration which brings about fermentation.
  • Fermentation of glucose mainly forms ethyl alcohol and carbon dioxide. It leaves the dough.
  • The leavened dough is baked. Both carbon dioxide and ethyl alcohol evaporate making the bread porous and soft.

Which of the following is a plant hormone?

  1. ((a))

    Insulin

  2. ((b))

    Cytokinin

  3. ((c))

    Thyroxin

  4. ((d))

    Oestrogen

Show Answer
Answer: ((b))

Cytokinin

The correct answer is Cytokinin.

Key Points 

  • Cytokinin:
  • Cytokinin is defined as a number of plant hormones that influence growth and the stimulation of cell division.
  • Cytokinins are synthesized in the roots and are usually derived from adenine.
  • They move upward in the xylem (woody tissue) and pass into the leaves and fruits, where they are required for normal growth and cell differentiation.
  • Cytokinins also act in conjunction with auxin (another plant hormone) to retard senescence, which, at least in its early stages, is an organized phase of metabolism and not just a breakdown of tissue.
  • An example of senescence is the yellowing of isolated leaves, which occurs as proteins are broken down and chlorophyll is destroyed.
  • Cytokinins prevent yellowing by stabilizing the content of protein and chlorophyll in the leaf and the structure of chloroplasts.

Additional Information 

  • Insulin:
  • Insulin is a kind of hormone that regulates the level of sugar (glucose) in the blood and that is produced by the beta cells of the islets of Langerhans in the pancreas.
  • Insulin is secreted when the level of blood glucose rises after a meal.
  • When the level of blood glucose falls, the secretion of insulin stops, and the liver releases glucose into the blood.
  • Insulin was first reported in pancreatic extracts in 1921, having been identified by Canadian scientists Frederick G. Banting and Charles H. Best and by Romanian physiologist Nicolas C. Paulescu, who was working independently and called the substance “pancreatin.”
  • After Banting and Best isolated insulin, they began work to obtain a purified extract, which they accomplished with the help of Scottish physiologist J.J.R. Macleod and Canadian chemist James B. Collip. Banting and Macleod shared the 1923 Nobel Prize for Physiology or Medicine for their work.
  • Thyroxin:
  • Thyroxine is one of the two major hormones secreted by the thyroid gland.
  • Thyroxine’s principal function is to stimulate the consumption of oxygen and thus the metabolism of all cells and tissues in the body.
  • Thyroxine is formed by the molecular addition of iodine to the amino acid tyrosine while the latter is bound to the protein thyroglobulin.
  • Excessive secretion of thyroxine in the body is known as hyperthyroidism, and the deficient secretion of it is called hypothyroidism.
  • Estrogen:
  • Estrogen is a group of hormones that primarily influence the female reproductive tract in its development, maturation, and function.
  • There are three major hormones estradiol, estrone, and estriol, among the estrogens, and estradiol is the predominant one.
  • The major sources of estrogens are the ovaries and the placenta (the temporary organ that serves to nourish the fetus and remove its wastes); additional small amounts are secreted by the adrenal glands and by the male testes.
  • It is believed that the egg follicle (the saclike structure that holds the immature egg) and interstitial cells (certain cells in the framework of connective tissue) in the ovaries are the actual production sites of estrogens in the female.
  • Estrogen levels in the bloodstream seem to be highest during the egg-releasing period (ovulation) and after menstruation when tissue called the corpus luteum replaces the empty egg follicle.

pollen grains

The correct answer is pollen grains.

Explanation:

  • The sexual reproductive part of angiosperms is called a flower.
  • It develops after the completion of the vegetative phase.
  • The flower contains a male part and a female part.
  • The male part is known as the stamen and the female part is known as the pistil.

Stamen has 2 parts:

  • Anthers -
  • It is a two-lobed structure that contains male spores called microsporangia for the production of pollen grains.
  • The anther contains pollen grains that have male gametes.
  • These pollen grains need to be moved to a part of the pistil called the stigma.
  • Stamen supports the anther.
  • Filaments -
  • It is a long stalk-like structure that connects the base of the flower with an anther which holds the anther in position.
  • The female part or pistil consists of Ovary, stigma, and style.
  • They are usually located in the center of the flower. It has 3 parts:
  1. Stigma-
  • It receives the pollen grains.
  • It has a sticky surface and pollen grains get stuck to it during pollination.
  1. Style-
  • It is a long tube-like structure, that connects the stigma with the ovary.
  1. Ovary-
  • It is the basal swollen part of the pistil that contains ovules and eggs.

Diagram of the Parts of a Flower | Parts of a flower, Flower structure,  Diagram of a flower

Additional Information 

  • Pollination refers to the transfer of pollen grains from the anther of a stamen to the stigma of a carpel.
  • It occurs in 2 ways:
  • Self-pollination: refers to the transfer of pollen grains from the anther of a flower to the stigma of the same flowers on the same plant.
  • Cross-pollination: refers to the transfer of pollen grains from the anther of a flower on one plant to the stigma of the flower on another plant.

Due to an increase of 30% in the price of eggs, 3 eggs less are available for Rs. 7.80. The present rate of eggs per dozen is

  1. ((a))

    Rs. 8.64

  2. ((b))

    Rs. 8.88

  3. ((c))

    Rs. 9.36

  4. ((d))

    Rs. 10.40

Show Answer
Answer: ((c))

Rs. 9.36

Given:

The cost of 3 eggs is Rs. 7.80.

increased percentage = 30%

Calculation:

Let original price of one egg = x

then 

Increased price of one egg = 1.3x

So

7.8x\frac{7.8}{x} - 7.81.3x\frac{7.8}{1.3x} = 3

⇒ 7.8(0.3/1.3x) = 3

⇒ x = 0.6

So

Increased price of one egg = 1.3 × 0.6 = Rs. 0.78

So present price of one dozen egg = 12 × 0.78 = Rs. 9.36

∴ The present rate of eggs per dozen is 9.36.

A cricketer has a certain average for 10 innings. In the eleventh innings, he scored 108 runs, thereby increasing his average by 6 runs. His new average is

  1. ((a))

    48 runs

  2. ((b))

    52 runs

  3. ((c))

    55 runs

  4. ((d))

    60 runs

Show Answer
Answer: ((a))

48 runs

Given:

Eleventh innings he scored 108 runs

increased average 6 runs

Calculation:

Let the average of cricketer after 10 innings be X.

Total runs scored by him after 10 innings = 10x

In the eleventh innings, he scored 108 runs

Total runs scored by him after 11 innings = 10x + 108.

his average is increased by 6 runs after 11 innings

⇒ (x + 6) = (10x+108)11\frac{(10x + 108)}{11}

⇒ 11x + 66 = 10x + 108

⇒ x = 42

∴ New average of the cricketer = 42 + 6 = 48 runs.

A two-digit number is such that the product of the digits is 8. When 18 is added to the number, then the digits are reversed. The number is

  1. ((a))

    18

  2. ((b))

    24

  3. ((c))

    42

  4. ((d))

    81

Show Answer
Answer: ((b))

24

Calculation:

Let the ten's and units digit be x and 8x\frac{8}{x} respectively

Then,

⇒ (10x + 8x\frac{8}{x}) + 18 = 10 × 8x\frac{8}{x} + x

⇒ 10x2 + 8 + 18x = 80 + x2

⇒ 9x2 + 18x - 72 = 0

⇒ x2 + 2x - 8 = 0

⇒ (x + 4)(x - 2) = 0

⇒ x = 2

So, ten's digit = 2 and unit's digit = 4.

Hence, required number is 24.

Ajay buys 4 horses and 9 cows for Rs. 13,400. If he sells the horses at 10% profit and cows at 20% profit, then he earns a total profit of Rs. 1,880. The cost of a horse is

  1. ((a))

    Rs. 1,000

  2. ((b))

    Rs. 2,000

  3. ((c))

    Rs. 2,500

  4. ((d))

    Rs. 3,000

Show Answer
Answer: ((b))

Rs. 2,000

Given:

CP = Rs. 13400

Horse profit % = 10%

Cows profit % = 20%

Profit earns = Rs. 1880

Calculation:

Let x be the cost price of horses and y be the cost price of cows.

Therefore, 4x + 9y = 13400 → (1)

Total Profit = 10% of 4x + 20% of 9y = 1880

⇒ 4x + 18y = 18800 → (2)

Subtract eq (2) and eq (1)

4x + 18y - 4x - 9y = 18800  - 13400

9y = 5400

y = 600

y = 600 substitute in eq (1), we get

4x + 9(600) = 13400

4x = 13400 - 5400

4x = 8000

x = 2000

∴ Price of horse = Rs. 2000.

At what rate percent per annum will the simple interest on a sum of money be 25\frac{2}{5} of the amount in 10 years?

  1. ((a))

    6236\frac{2}{3}%

  2. ((b))

    5235\frac{2}{3}%

  3. ((c))

    6%

  4. ((d))

    4%

Show Answer
Answer: ((a))

6236\frac{2}{3}%

Given:

Time = 10 years

SI = 25\frac{2}{5} of amount

Formula Used:

A = SI + P

SI = PTR100\frac{PTR}{100}

Calculation:

SI = 25\frac{2}{5} of amount

⇒ SI =  25\frac{2}{5} × A

⇒ SI = 25\frac{2}{5} × [SI + P]

​⇒ 5 SI = 2 SI + 2P

​⇒ 3 SI = 2P

​⇒ SI = 23\frac{2}{3}P

We know that SI = PTR100\frac{PTR}{100}

⇒ 23\frac{2}{3}P = P×10×R100\frac{P \times 10\times R}{100}

⇒ R = 203\frac{20}{3}

⇒ R = 6236\frac{2}{3} %

∴ The rate of interest is 6236\frac{2}{3} % .

Given:

R = 20%

Formula Used:

A = P(1 + R100\frac{R}{100})n

Calculation:

According to the question,

P(1 + 20100\frac{20}{100})n > 2P

⇒ (65\frac{6}{5})n > 2

Now (65\frac{6}{5} × 65\frac{6}{5} × 65\frac{6}{5} × 65\frac{6}{5}) > 2

So, n = 4 years.

Answer: ((c))

1

Given:

ax+yb=1\rm\frac{a}{x} + \frac{y}{b} =1 and by+zc=1\rm\frac{b}{y} + \frac{z}{c} =1

Calculation:

⇒ ax+yb=1\rm\frac{a}{x} + \frac{y}{b} =1

⇒ ax\frac{a}{x} = 1 - yb\frac{y}{b}

⇒ ax\frac{a}{x} = byb\frac{b-y}{b}

⇒ xa\frac{x}{a} =  bby\frac{b}{b-y} → (1)

Now, by+zc=1\rm\frac{b}{y} + \frac{z}{c} =1

⇒ zc\frac{z}{c} = 1 - by\frac{b}{y}

⇒ zc\frac{z}{c} = yby\frac{y - b}{y}

⇒ cz\frac{c}{z} = yyb\frac{y}{y - b} → (2)

Now we have to solve xa+cz\rm\frac{x}{a} + \frac{c}{z}

⇒ xa+cz\rm\frac{x}{a} + \frac{c}{z}  = bby\frac{b}{b-y} + yyb\frac{y}{y - b}

⇒ xa+cz\rm\frac{x}{a} + \frac{c}{z}  = bby\frac{b}{b-y}yby\frac{y}{b-y}

⇒ xa+cz\rm\frac{x}{a} + \frac{c}{z}  =  byby\frac{b -y}{b-y}

xa+cz\rm\frac{x}{a} + \frac{c}{z}  = 1.

  3. ((c))

    Rs. 4,000

  4. ((d))

    Rs. 4,400

Show Answer
Answer: ((c))

Rs. 4,000

Given:

Income Ratio A : B = 5 : 4

Expenditure ratio A : B = 3 : 2

Each Savings = Rs. 1600

Formula Used:

Savings = Income - Expenditure

Calculation:

Let x be the multiple of income and y be the multiple of expenditure

A's income = 5x and A's expenditure = 3y

B's income = 4x and B's expenditure = 2y

According to the question:

5x - 3y = 1600 → (1)

4x - 2y = 1600 → (2)

Now, eq(1) is multiply with 2 and eq(2) is multiply with 3 to get the required answer

10x - 6y = 3200 → (3)

12x - 6y = 4800 → (4)

(4) - (3)

12x - 6y - 10x + 6y = 4800 - 3200

2x = 1600

x = 800

∴ The income of A is 5x = 5 × 800 = Rs. 4000.
