Given:

A sum increases by 75% in 10 years at a certain rate of simple interest per annum

Concept used:

Simple Interest, SI = (P × R × T) ÷ 100

where

P = Principal amount

R = Rate of interest per year

T = Time in years

Calculation:

Let the rate of interest and principal amount be R% and Rs. P respectively,

According to the question,

P + (P × R × 10) ÷ 100 = 1.75 × P

⇒ R = 7.5%

Hence, the sum becomes after 6 years = P + (P × 7.5 × 6)/100 = Rs. 1.45P

Thus, the sum becomes increases by = = 45%

∴ By 45% the same sum will increase in 6 years at the same rate of simple interest per annum.

The correct answer is Egypt.
Key Points

• The Nile is the longest river in the world.
• It flows across the eastern African region from South to North.
• The major portion of the river flows in Egypt.

The correct answer is rate of change of consumption as income changes​.
Key Points

• Marginal propensity to consume refers to the change in consumption with respect to the change in income.
• When there is an increase in income it reflects in better purchasing power of a consumer.
• The change in income not only affects consumption but also induces changes in savings.
• The proportion of consumption depends upon the income levels and corresponding necessities of the consumer.
• It is used widely in economics to calculate the required additional production for the increased demand(consumption).

Additional Information

• The complement of the MPC( Marginal propensity to Consume) is Marginal Propensity to Save(MPS).
• They both reflect the increase in income.
• Marginal Propensity To Consume (MPC)-
  • ​​​​​​​In economics, the marginal propensity to consume (MPC) is defined as the proportion of an aggregate raise in pay that a consumer spends on the consumption of goods and services, as opposed to saving it. The marginal propensity to consume is a component of Keynesian macroeconomic theory and is calculated as the change in consumption divided by the change in income.
  • The marginal propensity to consume is equal to ΔC / ΔY, where ΔC is the change in consumption, and ΔY is the change in income. If consumption increases by 80 cents for each additional dollar of income, then MPC is equal to 0.8 / 1 = 0.8.

The correct answer is indifference curve.
Key Points

• The optimum bundle of the consumer is located at the point where the budget line is tangent to one of the indifference curves.
• The indifference curve is a geometrical device developed by J.R. Hicks and R.G.D. Allen in the article “A Reconsideration of the Theory of Value”.
• An indifference curve shows a combination of two goods that give a consumer equal satisfaction and utility thereby making the consumer indifferent.
• An indifference schedule is a table which represents various combinations of two goods, which yield equal satisfaction to the consumer.
• The graphical presentation of the Indifference schedule is known as the Indifference curve.
• Along the curve, the consumer has an equal preference for the combinations of goods shown—i.e. is indifferent about any combination of goods on the curve.
• Typically, indifference curves are shown convex to the origin, and no two indifference curves ever intersect.
• A diagram showing different indifference curves corresponding to different indifference schedules of the consumer is an indifference map. In other words, a set or family of indifference curves is an indifference map.

• Law of Demand
• According to the law of demand
  • ​​​​when the price of a commodity increase, the quantity demanded decreases
  • when the price of a commodity decreases, it’s the quantity demanded increases
  • keeping other factors remains the same.
• The consumer’s demand for goods must be inversely related to the price of the good.
• There is an inverse relationship between price and demand and due to this the demand curve always has a downward slope.
• The demand curve is the relation between the quantity of the good chosen by a consumer and the price of the good.
• ​Assumptions for the Law of Demand
  • ​​No change in the income of consumers
  • No change is the taste and preference of the consumers
  • No change in price related to other goods.

The correct answer is Lipase.

Key Points

• Lipase enzymes are used in the stabilization of rice bran oil.
• Rice bran oil is known as wonder oil and it is the most important vegetable oil in Asia.
• Rice bran oil is extracted from bran which is the outer hard layer of rice.
• It is an emerging category in edible oil with a lot of nutritional properties and health benefits.
• Rice bran oil is heart-friendly, immunity, and prevents other diseases.
• The current study aimed to stabilize rice bran oil through different probiotic isolates and to assess the nutritional content of rice bran oil after stabilization.
• The study was aimed to inactivate naturally occurring lipases that can hydrolyze oil into glycerol and free fatty acid which is a serious problem that gives it a rancid taste and smell.

Additional Information

• Hydrolases are the group of enzymes that catalyze bond cleavages by reaction with water. The natural function of most hydrolases is digestion to break down nutrients into smaller units for digestion.
• Catalase is a key enzyme that uses hydrogen peroxide, a non-radical ROS, as its substrate. This enzyme is responsible for neutralization through the decomposition of hydrogen peroxide, thereby maintaining an optimum level of the molecule in the cell which is also essential for cellular signaling processes.
• Cellulase is any of several enzymes produced chiefly by fungi, bacteria, and protozoans that catalyze cellulolysis, the decomposition of cellulose and of some related polysaccharides. The name is also used for any naturally occurring mixture or complex of various such enzymes, that act serially or synergistically to decompose cellulosic material.

Given that:-

• No of days from 2 January 2017 to 31 March 2017 = 30 + 28 + 31 = 89 as 2017 is a non-leap year.
• Since, it was Thursday on 1 January 2017, every 7th day from 1 January will be a Thursday.
• Thus, no. of odd days = 89/7 = 5
• Now, 1 January 2017 (Thursday) + 5 odd days = 31 March 2017 (Tuesday)
• 31^st March 2017 will be Tuesday.

Hence, "option 2" is the correct answer.

The logic followed here is:-

From option 1:-

• (22, 34)
• 22 × 2 = 44 - 10 = 34

From option 2:-

• (11, 12)
• 11 × 2 = 22 - 10 = 12

From option 3:-

• (25, 42)
• 25 × 2 = 50 - 10 = 40 ≠ 42,
• It is different from others.

From option 4:-

• (17, 24)
• 17 × 2 = 34 - 10 = 24

Hence, "option 3" is the correct answer.

Given:

A man can do work in 20 days and a woman can do the same work in 30 days.

Concept used:

Total work = Efficiency (Work done per day) × Total time taken

Calculation:

⇒ LCM (20, 30) = 60

Let the total work be the LCM of the time taken by the individuals.

Hence, the total work = 60 units

Efficiencies,

⇒ 1 man does each day = 60 ÷ 20 = 3 units

⇒ 1 women does each day = 60 ÷ 30 = 2 units

⇒ Time is taken by the mentioned workforce to finish the work 
⇒  = 5 days

∴ In 5 days 2 men and 3 women will do the work.

⇒ πR² = 7546

∴ The area of the circle is 7546m².

The correct answer is Tauktae.
Key Points

• Cyclone Tauktae
  • It was the first cyclonic storm of 2021 that emerged from the Arabian Sea.
  • It hit southern Gujarat on 17 May 2021 and was classified as a Very Severe Cyclonic Storm (VSCS).
  • It is a tropical cyclone, It has been named by Myanmar.
  • It means 'gecko', a highly vocal lizard, in the Burmese language.

Additional Information

• Tropical Cyclones
  • Tropical cyclones are violent storms that originate over oceans in tropical areas and move over to the coastal areas bringing about large-scale destruction due to violent winds (squalls), very heavy rainfall (torrential rainfall) and storm surge.
  • They are irregular wind movements involving the closed circulation of air around a low-pressure centre.
  • Conditions Favourable for Tropical Cyclone Formation
    • Large sea surface with a temperature higher than 27° C,
    • The presence of the Coriolis force is enough to create a cyclonic vortex,
    • Small variations in the vertical wind speed,
    • A pre-existing weak low-pressure area or low-level-cyclonic circulation,
    • Upper divergence above the sea level system.
  • The depth of warm water (26-27°C) should extend for 60-70 m from the surface of the ocean/sea, so that deep convection currents within the water do not churn and mix the cooler water below with the warmer water near the surface.
  • The above condition occurs only in western tropical oceans because of warm ocean currents (easterly trade winds push ocean waters towards the west) that flow from the east towards the west forming a thick layer of water with temperatures greater than 27°C. This supplies enough moisture to the storm.
  • The cold currents lower the surface temperatures of the eastern parts of the tropical oceans making them unfit for the breeding of cyclonic storms.

Hence, "option 3" is the correct answer.

Given:

First observation: 29, 36, 21, 18, 7, 19, k, k ; mean = 21.25

Second observation: 29, 22, 15, 15, 22, 18, 21, p, p; mode = 29.

Concept used:

The mode is the most frequently occurring value on the list.

Total = Mean (Average) × number of entities

Calculation:

The mean of the observations first observation = Sum (29, 36, 21, 18, 7, 19, k, k) ÷ 8

According to the question,

Sum (29, 36, 21, 18, 7, 19, k, k) ÷ 8 = 21.25

⇒ 130 + 2k = 170

⇒ k = 20

The mode of the observations second observation = 29

Hence, p has to be 29 i.e. P = 29

Thus,

(p - k)

⇒ 29 - 20

⇒ 9

∴ The value of (p - k) is 9.
