Concept used:

Calculation:

∴ Required answer is 7/2.

The correct answer is Dr Shakuntala Haraksingh Thilsted.
Key Points

• Dr. Shakuntala Haraksingh Thilsted, a global nutrition expert of Indian descent, has won the prestigious 2021 World Food Prize.

Given:
The difference between the outer circumference and the inner circumference of the racing track is 33 m
Concept used:
Circumference of a circle = 2πr
Here r = radius
Calculation:
According to the question,

Let the radius of the outer circle be R and the inner circle be r
Now,
2πR - 2πr = 33
⇒ 2π(R - r) = 33
⇒ (R - r) = 33 × (1/2π)
⇒ (R - r) = 33 × (7/44)

Concept used:

Divisibility rule of 3 = Sum of the digits must be divisible by 3

Divisibility rule of 10 = Last two digits must be divisible by 10

Calculation:

According to the concept,

The number should be divisible by both 3 and 10

Now, from the options, all the numbers are divisible by 10 as their last two digits are divisible by 10

Now,

Option 1:

3 + 4 + 5 + 6 + 0 = 18 which is divisible by 3

Option 2:

4 + 5 + 6 + 7 + 0 = 22 which is not divisible by 3

Option 3:

2 + 3 + 4 + 5 + 0 = 14 which is not divisible by 3

Option 4:

1 + 2 + 3 + 4 + 0 = 10 which is not divisible by 3

∴ Required answer is Option 1.

Given:
The number should be divisible by 72, 108, and 300
Concept used:
For this type of question, we use the LCM method to find the required number
Calculation:
72 = 2³ × 3²
108 = 2² × 3³
300 = 2² × 3 × 5²
LCM = 2³ × 3³ × 5²
⇒ 5400
Now the number should be a cubic number and multiple of 5400
So,
5400 × 2 = 10800 which is not a cubic number
5400 × 3 = 16200 which is not a cubic number
5400 × 5 = 27000 which is a cubic number and the smallest
∴ The smallest cubic number, divisible by 72,108 and 300 is 27000.

The correct answer is 3 books.
Key Points
Beginning in 1589, Abu’l Fazl worked on the ‘Akbar Nama’ for thirteen years.

Additional Information

Given:
The length of each edge of a cube is 2.6 cm
Concept used:
The total surface area of the cube = 6a²
a = length of a side or edge of a cube
Calculation:
The total surface area of the cube = 6 × 2.6²
⇒ 6 × 6.76
⇒ 40.56
So, the total surface area of the cube is 40.56 cm²
∴ The total surface area (in cm2) of the cube is 40.56.

The correct answer is 8th Schedule.
Key Points

• Schedule VIII of the Indian constitution has given recognition to 22 languages.
• Initially, there were 14 languages in the eighth schedule of our constitution.
• 21^st Constitutional Amendment Act (CAA) 1967 added one language (Sindhi), 71^st CAA, 1992 added 3 (Konkani, Manipuri and Nepali).
• 92^nd CAA od 2003 added Bodo, Dogri, Maithili, Santhali to the eighth schedule making a total of 22 languages.

Additional Information

• English and Hindi are the languages declared by our constitution for transacting business in the Parliament.
• English and Hindi are the official languages of India.
• There is no national language of India as mentioned by the constitution of India.

Given:

Sudhir is 4.5 times as efficient as Aarav.

They can complete a piece of work in 8 days.

Concept used:

Total work = effective efficiency of the workers × time taken by them

Calculation:

Let the efficiency of Aarav be A

So, the efficiency of Sudhir = 4.5 × A = 4.5A

Effective efficiency = 4.5A + A = 5.5A

Total work = 5.5A × 8

⇒ 44A

Now,

Time is taken by Aarav to the same work alone = 44A/A

⇒ 44 days

∴ Aarav will take 44 days to do the same work alone.

The correct answer is Rajnath Singh.

Key Points

• Defence Minister Rajnath Singh has approved the policy on archiving, declassification and compilation/publication of war/operations histories by the Ministry of Defence.
• The policy envisages that each organisation under the Ministry of Defence will transfer the records to the History Division of the Ministry of Defence for proper upkeep, archival and writing of the histories.

Given:

A can complete 12% of the work in 15% of the allotted time

Calculation:

Let the total time taken by them be 100 minutes

So, 15% of 100 minutes = 15 minutes

Now,

12% of work is completed in 15 minutes by A

4% of work is completed in 5 minutes by A

80% of work is completed in 100 minutes by A

If A can complete 80% in 100 minutes then, B will complete remaining portion i.e (100 - 80) = 20%

∴ 20% of the work was done by B.

Given statements: K = P < C; P > Q; Q > L

On combining: L < Q < K = P < C

Conclusions:

I. Q < C → True (as L < Q < K = P < C gives Q < C).

II. K > L → True (as L < Q < K = P < C gives K > L).

Hence, the correct answer is “Both conclusions I and II are true”.

Given:

A family spends Rs. 4,600, Rs. 5,600, Rs. 4,800, Rs. 3,800, and Rs. 6,000 on groceries in the first 5 months of a year.

Average expenditure to be maintained throughout 6 months = Rs. 4500

Concept used:

Total = Average × Number of entities

Calculation:

Total expenture on groceries as of 5th month = Rs. (4,600 + 5,600 + 4,800 + 3,800 + 6,000) = Rs. 24,800

Total expenditure has to be maintained according to the average = Rs. (4500 × 6) = Rs. 27000

Hence, the expenditure on groceries in the 6th month = Rs. (27000 - 24800) = Rs. 2200

∴ The family should spend Rs. 2,200 in the 6th month to make the 6 months average spending of the family on groceries to Rs. 4,500.

Odd days:

A non-leap year has 365 days and a leap year has 366 days.

Non-leap year = 365 days or 52 weeks and 1 day. So, here the number of odd days is 1.

Leap year = 366 days or 52 weeks and 2 days So, here the number of odd days are 2.

• So, total number of odd day between 2006 and 2007 = 1 (Total Non- leap year) = 1 odd day

Thursday on February 1, 2007

=> Day on 1 February 2006 = Thursday – 1 = Wednesday

Therefore, 1 February 2006 = Wednesday

Now,

• February 2, 2006 = 1 February 2006 + 1 day

= Wednesday + 1

= Thursday

Hence, February 2, 2006 was “Thursday”.

Given:

A train running at 90 km/h crosses an electric pole in 18 seconds and a platform in 65 seconds.

Concept used:

1m/s = 18/5 km/h

While a train crosses a platform, it crosses the sum of its length and the length of the platform

While a train crosses an electric pole, it crosses its own length.

Calculation:

Let the length of the platform be P meters.

90 kmph = 90 ÷ 18/5 = 25 meters per second (mps)

Hence, the length of the train = 25 × 18 = 450 meters.

According to the question,

25 × 65 = (450 + Q)

⇒ 1625 = 450 + Q

⇒ Q = 1175

∴ The length of the platform is 1175 m.

According to the given information

‘watch’ is coded as "7".
Hence, '7' is the correct answer.

The correct answer is Average product.

Key Points

• The average product, also known as the output per unit of factor inputs or the average of the total product per unit of input, is determined by dividing the Total Product by the inputs (variable factors).

Additional Information

• The average cost per unit of production (AC) is also known as the average total cost (ATC). Divide the total cost (TC) by the quantity produced by the company (Q) to find it. The average cost has a significant impact on how companies price their goods.
• Firms' sales of specific commodities are directly proportional to the size of the market and how their competitors choose to operate.
• With cost on the vertical axis and quantity on the horizontal axis, an average cost curve can be shown.
• The average fixed cost (AFC) is calculated by dividing the fixed costs of production (FC) by the quantity (Q) of output generated.
• The variable cost per unit is the average variable cost in economics. The entire variable cost is divided by the output to get the average variable cost.

Calculation:
Total expenditure of 2017 = 361 + 93 + 83 + 142 + 52 = 731 Lakh
Total expenditure of 2021 = 652 + 111 + 132 + 101 + 75 = 1071 Lakh
% = (731/1071) x 100% ≈ 68.253% ≈ 68%
∴ The company's total expenditure in 2017 was approximately 68% of its total expenditure in 2021.
