Given:

Formula Used: 

Total Seats = Enrolled Seats + Vacant Seats

Calculation:

Vacant seats in 2016 = 230 - 180 = 50

Vacant seats in 2017 = 230 - 207 = 23

Vacant seats in 2018 = 230 - 200 = 30

Vacant seats in 2019 = 230 - 211 = 19

Vacant seats in 2020 = 230 - 195 = 35

∴ Year which has the minimum vacant seats is 2019

Given:

Percentage increase in enrollment of students from 2016-2017 is

In BTech = [(110 - 96)/96] × 100 = (14/96) × 100 = 14.58%

In MTech = [(26 - 24)/24] × 100 = (2/24) × 100 = 8.33%

In MPhil = [(14 - 12)/12] × 100 = (2/12) × 100 = 16.66%

In MBA = [(57 - 52)/52] × 100 = (5/52) × 100 = 9.61%

∴ The course which has the highest percentage increase in enrollment of students from 2016-2017 is MPhil.

Given:  

Calculation:

The number of vacant seats of B.Tech for years (2016-2020) is

In the year 2016 = 120 - 96 = 24

In the year 2017 = 120 - 110 = 10 

In the year 2018 = 120 - 108 = 12

In the year 2019 = 120 - 112 = 8

In the year 2020 = 120 - 104 = 16

So, the average number of vacant seats of B. Tech for years (2016-2020) is

⇒ (24 + 10 + 12 + 8 + 16)/5

⇒ 70/5 = 14

∴ The average number of vacant seats of B. Tech for years (2016 - 2020) is 14

Given: 

Formula Used:

Total Seats = Enrolled Seats + Vacant Seats

Calculation:

Vacant Seats in MTech for 2016-2020 = (30 - 24) + (30 - 26) + (30 - 25) + (30 - 28) + (30 - 27) 

Now, average vacant seats of M Tech = (6 + 4 + 5 + 2 + 3)/5

⇒ 20/5 = 4

Vacant Seats in MBA for 2016-2020 = (60 - 52) + (60 - 57) + (60 - 54) + (60 - 56) + (60 - 48) 

Now, average vacant seats of M Tech = (8 + 3 + 6 + 4 + 12)/5

⇒ 33/5 = 6.6

So, the difference between average vacant seats of M Tech and MBA for 2016-2020 = 6.6 - 4 = 2.6

∴ The difference between average vacant seats of M Tech and MBA for 2016-2020 is 2.6

CONCEPT:

Diamond Price vs Weight

• The price of diamonds increases linearly with the weight of the diamond, as shown by the given graph.
• The price is given in lakhs, and the weight is in carats.
• The price at Rs. 4.5 lakh corresponds to a specific carat weight based on the line equation derived from the graph.

EXPLANATION:

• The graph shows a linear relationship between the price (in lakhs) and the weight (in carats) of diamonds.
• From the graph, Rs. 5 lakh corresponds to 2.5 carats, which represents the maximum carat size for Rs. 5 lakh.
• By drawing a line at Rs. 4.5 lakh, we find that the corresponding weight is 2.25 carats, which is the largest diamond that can be purchased for Rs. 4.5 lakh.

Therefore, the largest diamond that can be purchased for Rs. 4.5 lakh is 2.25 carats.

Given:

Percentage of Taxes = 5

Percentage of Interest on Loans = 7.5

Calculation: 

Difference between the expense of Interest on Loans and Taxes = 7.5 - 5

⇒ 2.5 

∴ The required percentage = 2.5/5 × 100 

⇒ 50%

Formula used:

Percentage Increase = [\(\dfrac{Final\; Value- Initial \;Value}{Initial \;Value}\)] × 100

Calculation: 

Increase percent in 2015 = (350 - 320)/ 320 × 100 = 30/320 × 100 = 9.37%

Increase percent in 2016 = (380 - 350)/ 350 × 100 = 30/350 × 100 = 8.57%

Increase percent in 2017 = (400 - 380)/ 380 × 100 = 20/380 × 100 = 5.26%

Decrease percent in 2018 = (400 - 280)/ 400 × 100 = 120/400 × 100 = 30%

Increase percent in 2019 = (300 - 280)/ 280 × 100 = 20/280 × 100 = 7.14%

∴ In 2017 the percentage increase in the revenue as compared to its preceding year is below 6%.

Calculation:

Total production = (600 + 628 + 750 + 500 + 570) tones = 3048 tons

Total sales = (450 + 525 + 500 + 400 + 516) tons = 2391 tons 

∴ Percentage of the total sales = 2391/3048 × 100 

⇒ 78.44%

Formula used:

Percentage Increase = (Production of current year - Production of previous year)/ Production of Previous year × 100

Calculation:

Percentage increase in the production of medicines of the year 2011 = (60 - 40)/40 × 100 = 20/40 × 100 = 50%

Percentage increase in the production of medicines of the year 2015 = (80 - 60)/60 × 100 = 20/60 × 100 = 100/3%

∴ The required ratio = 50% : 100/3%

⇒ 1 : 2/3

⇒ 3 : 2

Calculation:

In 2015, No. of employees in all department = 20 + 40 + 50 + 70 + 80 + 30 = 290

In 2018, No. of employees in all department = 30 + 70 + 80 + 90 + 60 + 30 = 360

Difference = 360 - 290 = 70

According to question,

No of employees added = 80

Fired employees from C = 80 - 70 = 10

Strength of C in 2018 = 80              (Given)

If not fired, strength of C in 2018 = 80 + 10 = 90

Strength of department C in 2018 would have been greater by = (10/80) × 100

⇒ 12.5%

∴ Option 1 is the correct answer.

Given:

No of the students who obtained marks between 200 and 300

⇒ 45 + 60 = 105 

No of students who obtained marks between 350 or more marks

⇒ 40 + 35 = 75

Calculation:

⇒ The required percent = (105 - 75)/75 × 100

⇒ 30/75 × 100 

⇒ 40%

∴ The answer is 40%.

Calculation:

Average Export diamonds for 7 years = Total export / Total no of years

⇒ (7.2 + 8.5 + 9.8 + 10.9 + 11.8 + 11.5 + 12.4)/7 = 72.1/7 

⇒ 10.3 crores

In the given 4 years, the export is more than the average export:

⇒ 2011 = 10.9 crores

⇒ 2012 = 11.8 crores

⇒ 2013 = 11.5 crores 

⇒ 2014 = 12.4 crores

∴ The no of years where export is more than the average export is 4. 

Calculation:

Sum of the imports in 2015 & 2018 = 390 + 450 = 840 crore

Sum of the exports in 2014 & 2017 = 300 + 420 = 720 crore

∴ The required ratio = 720 : 840 

⇒ 6 : 7

Given:

No. of lecturers in state A in 2017 = 10

No. of lecturers in state B in 2019 = 22

Formula used:

Percentage = \(\frac{\text{Lecturer in state A}}{\text{Lecturer in state B}}\times 100\)

Calculations:

According to the formula,

⇒ Percentage = \(\frac{10}{22}\times100\) = 45.45%

⇒ Hence, No. of lecturers in state A in 2017 is 45.45% of state B in 2019

Given:

Production of company P in 2015 = 80 lakh tonnes

Production of company P in 2019 = 120 lakh tonnes

Calculation:

∴ The required percentage increase in 2019 = (120 - 80)/80 × 100

⇒ 40/80 × 100 = 50%
