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

The correct answer is HORVITHA

Explanation:

The name Petreversia hints Pet Reverse-ia", i.e., the land of reversed "pets".

1) TANGODIN: Contains "GOD" → which is "DOG" reversed 

2) PATACAHON: Contains "TAC" → which is "CAT" reversed 

3) BACCANEH: Contains "NEH" → which is "HEN" reversed 

4) HORVITHA is the odd one out because it does not contain any common pet name in reverse, unlike the other three.

Given:

The batsman scores 97 runs in the 15th inning.

This increases his average by 5 runs.

Formula used:

Average = Total runs / Number of innings

Solution:

Let x be the batsman's average after 14 innings.

We know that the total runs scored by the batsman in 14 innings is 14x.

According to the question:

14x + 97 = 15(x + 5)

14x + 97 = 15x + 75

x = 22

Average after 15th innings  = x + 22 = 5 + 22 = 27

∴ Option 3 is the correct answer.

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%

Given data:

A's time for 80 pages: 4 hours

B's time for 80 pages: 3 hours 20 minutes

Concept: Work and time ratio.

Calculation:

The ratio of work rates of A and B = B's time/A's time = 4/3.333 = 1.2

Ratio of pages = 1.2 : 1 = 6 ∶ 5

A's share of 121 pages = 5/11 × 121 = 55 pages

Hence, A had to type 55 pages.

Given:

Speed from station P to station Q: 70 km/h

Speed from station Q to station P: 90 km/h

Formula:

Average speed = 2xy/x + y

Solution:

Average speed = (2 × 70 × 90)/70 + 90 = 78.75 km/h

Therefore, the average speed of the bus during the entire journey is 78.75 km/h

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.
