Solution:

Total students who scored less than 40 marks = 8

The total number of students = Sum of all students = 10

Number of students who scored more than 40 marks 

⇒ Total students - Students scored less than 40 marks

⇒ 10 - 8 = 2

∴ 2 students scored more than 40 marks.

Given:

The given table shows the number of new employees who joined in different categories of employees in an organisation and also the number of employees from these categories who left the organisation every year since the foundation of the organisation in 2015. 

Calculations:

According to the question,

Total Accountants working = Total joined - Total left

Working = (35 + 26 + 15 + 20 + 14) - (16 + 5 + 38 + 24)

Working = 110 - 83 = 27

∴ The total number of accountants working in the organization in the year 2019 is 27.

Calculation:

J1 = (50 + 100)/2

⇒ 150/2

⇒ 75

J2 = (90 + 120 + 30 + 80 + 80 + 50)

⇒ 450

So, J2/J1 = 450/75

⇒ 6

∴ The required answer is 6.

Calculation:

The percentage of candidates that qualified from Goa over those that appeared from Goa in 2012

⇒ (810/7800) × 100 = 10.38

The percentage of candidates that qualified from Goa over those that appeared from Goa in 2013

⇒ (800/7500) × 100 = 10.66

The percentage of candidates that qualified from Goa over those that appeared from Goa in 2014

⇒ (920/8800) × 100 = 10.45

The percentage of candidates that qualified from Goa over those that appeared from Goa in 2015

⇒ (850/7200) × 100 = 11.80

∴ The correct option is 4

Calculation:

No. of students who scored less than 20 = 5

No. of students who scored less than 30 = 6

So, the number of students who scored marks between 20 and 30 = 6 - 5

⇒ 1

∴ The required answer is 1.

Calculation:

Total number of players participating in game A = 31 + 24 + 18 + 29 + 12 + 40

⇒ 154

Total number of players participating in game B = 58 + 36 + 26 + 37 + 33 + 44

⇒ 234

Ratio = 154 : 234

⇒ 77 : 117

∴ Ther required answer is 77 : 117.

Given:

Data regarding the population of a city at the end of the years mentioned.

Formula used:

Rate of increase = (population in current year - population in previous year) / (population in previous year) × 100

Calculation:

The rate of increase for a given year compared to the previous year can be calculated by using above formula.

Lets calculate the rate of increase for a given year compared to the previous year, 

Rate of increase in 2013 = \(\frac{68.4-64.5}{64.5}\times 100\) = 6.04

Rate of increase in 2014 = \(\frac{72.6-68.4}{68.4}\times 100\) = 10.93

Rate of increase in 2015 = \(\frac{83.8-72.6}{72.6}\times 100\) = 15.42

Rate of increase in 2016 = \(\frac{100.6-83.8}{83.8}\times 100\) = 20.4

Rate of increase in 2017 = \(\frac{112.8-100.6}{100.6}\times 100\) = 12.12

Rate of increase in 2018 = \(\frac{128.4-112.8}{112.8}\times 100\) = 13.8

Rate of increase in 2019 = \(\frac{134.6-128.4}{128.4}\times 100\) = 4.82

Rate of increase in 2020 = \(\frac{156.8-134.6}{134.6}\times 100\) = 16.49

Rate of increase in 2021 = \(\frac{176.4-156.8}{156.8}\times 100\) = 12.5

2016 has the highest rate of increase compared to the previous year which is 20.4%

Given:

Wages of Rahul in November = ₹11500

Wages of Sunil in November = ₹10500

Formula used:

Percentage = \(\dfrac{\text{Wages of Sunil}}{\text{Wages of Rahul}} \times 100\)

Calculation:

⇒ Percentage = \(\dfrac{10500}{11500} \times 100\)

⇒ Percentage = \(\dfrac{10500 \times 100}{11500}\)

⇒ Percentage = 91.30%

∴ Sunil's wages in November are 91.30% of Rahul's wages in November.

Given:

Production of A-type cars in 2012: 1750 (thousand)

Production of A-type cars in 2013: 1800 (thousand)

Production of A-type cars in 2014: 2950 (thousand)

Production of B-type cars in 2013: 2950 (thousand)

Production of B-type cars in 2014: 3020 (thousand)

Production of B-type cars in 2015: 3240 (thousand)

Production of C-type cars in 2013: 2070 (thousand)

Production of C-type cars in 2014: 3150 (thousand)

Production of C-type cars in 2015: 3290 (thousand)

Calculations:

Calculate the average production of A-type cars (2012-2014):

Average production of A-type cars = (1750 + 1800 + 2950) / 3 = 6500/3 

Calculate the combined average production of B-type and C-type cars (2013-2015):

Combined average production of B-type cars and C-type cars

= (2950 + 3020 + 3240 + 2070 + 3150 + 3290) / 6 

= 17,720/6 = 8860/3

Calculate the difference between the averages:

Difference = 8860/3 - 6500/3 = 2360/3 

Calculate the percentage difference:

Percentage difference = (2360/3 / 8860/3) × 100 = 26.6% (rounded to 1 decimal place)

Therefore, the average number of A-type cars produced by the company during 2012 to 2014 is 26.6% less than the combined average number of B-type and C-type cars produced by the company from 2013 to 2015.

Calculation:

Total amount of salary in 4 years = 200000 + 250000 + 300000 + 350000 = Rs.1100000

Average amount of salary in four years = 1100000/4 = Rs.275000

∴ The correct answer is Rs.275000.
