Productivity of vegetable = Productivity of Potato + Productivity of Tomato + Productivity of Onion

Productivity of vegetable (In 2014) = 550 Tonne

Productivity of vegetable (In 2015) = 570 Tonne

Productivity of vegetable (In 2016) = 440 Tonne

Productivity of vegetable (In 2017) = 580 Tonne

Productivity of vegetable (In 2018) = 1270 Tonne

Productivity of vegetable (In 2019) = 1490 Tonne

#### Show Answer With Best Explanation

Explanation:

Total Capacity of Reneable Energy in the year 2015 = 10 + 15 + 8 +12 = 45
Total Capacity of Reneable Energy in the year 2019 = 22 + 24 + 20 + 20 = 86

Formula:

Increase Percentage
= (Total Capacity in year 2019 – Total Capacity in year 2015) X 100 / Total Capacity in year 2015
= (86 – 45) X 100 / 45
= 4100 / 45
= 91.11 %

91.11 % is over-all increase (%) in installed capacity of Reneable Energy in the year 2019, with reference to 2015.

So, The Correct Answer is Option (II).

#### Show Answer With Best Explanation

Explanation:

Formula :
Growth Percentage = (Final value – Initial value) X 100 / Initial value
Average Growth = Total Growth / Number of Growth Years

The Growth Percentage in Year 2015 & 2016 = (18-15) X 100 / 15 = 300/15 = 20 %
The Growth Percentage in Year 2016 & 2017 = (20-18) X 100 / 18 = 200/18 = 11.11 %
The Growth Percentage in Year 2017 & 2018 = (20-20) X 100 / 20 = 0/20 = 0 %
The Growth Percentage in Year 2015 & 2016 = (24-20) X 100 / 20 = 400/20 = 20 %

Total in Given 5 years = 20% + 11.11% + 0% + 20% = 51.11%

Average Growth = 51.11% / 4 = 12.77%

Note:
Don’t be confused with Number of Years. Total 5 Years are given, but Total Growth Years are only 4.

For the country â€˜Yâ€™ , 12.77 % is the average annual growth (%) of Renewable Energy capacity.

So, The Correct Answer is Option (II).

#### Show Answer With Best Explanation

Explanation:

According to question, we need
Total Employee of Department E in year 2018 &
Total Employee of Department D in year 2019

Given,
Percentage of Employee of Department E in year 2018 = 8% &
Percentage of Employee of Department D in year 2019 = 20%

Total Employee in year 2018 = 18000 &
Total Employee in year 2019 = 20000

Total Employee of Department E in year 2018 = Total employee in 2018 X Percentage of Employee of Department E in year 2018
= 18000 X 8%
= 18000 X 8 /100
= 1440

Total Employee of Department D in year 2019 = Total employee in 2019 X Percentage of Employee of Department D in year 2019
= 20000 X 20%
= 20000 X 20 /100
= 4000

Ratio = 1440 / 4000 = 9/25

The ratio of Total Employee of Department E in year 2018 compared to Total Employee of Department D in year 2019 is 9:25.

So, The correct answer is Option (I)

#### Show Answer With Best Explanation

Explanation:

According to Question, we need
Total number of Employee of Department A in 2018.

Given,
Percentage of Employee of Department A in year 2018 = 22%
Total Number of Employee in year 2018 = 18000
Average monthly salary of employees of Department A in 2018 = 24000

We can find,
Total number of Employee of Department A in 2018 = Total employee in 2018 X Percentage of Employee of Department A in year 2018
= 18000 X 22%
= 18000 X 22/100
= 3960

Total salary Expenses of the department A in 2018
= Total number of Employee of Department A in 2018 X Average monthly salary of employees of Department A in 2018
= 3960 X 24000
= 95040000
= 9.5 crores

So, The correct answer is Option (IV)

Department B has Maximum variation of employee strength in 2019 with reference to 2018.

So, The Correct Answer is Option (II).

#### Show Answer With Best Explanation

Explanation:

According to question, we need
Total Employee of Department B in year 2018 &
Total Employee of Department B in year 2019

Given,
Percentage of Employee of Department B in year 2018 = 23% &
Percentage of Employee of Department B in year 2019 = 26%

Total Employee in year 2018 = 18000 &
Total Employee in year 2019 = 20000

Total Employee of Department B in year 2018
= Total employee in 2018 X Percentage of Employee of Department B in year 2018
= 18000 X 23%
= 18000 X 23 /100
= 4140

Total Employee of Department B in year 2019
= Total employee in 2019 X Percentage of Employee of Department B in year 2019
= 20000 X 26%
= 20000 X 26 /100
= 5200

It is Given that, 300 employees had left the department – B at the end of 2018.
Remaining Employee of Department B in year 2018 = 4140 – 300 = 3840.

& we have calculated that Total Employee of Department B in year 2019 =5200
Difference = 5200 – 3840 = 1360

1360 new employees joined in 2019 in the department – B

So, The Correct Answer is Option (III).

#### Show Answer With Best Explanation

Explanation:

Given,
Percentage of Employee of Department B in year 2018 = 23% &
Percentage of Employee of Department B in year 2019 = 26%

Total Employee in year 2018 = 18000 &
Total Employee in year 2019 = 20000

Total Employee of Department C in year 2018
= Total employee in 2018 X Percentage of Employee of Department C in year 2018
= 18000 X 18%
= 18000 X 18 /100
= 3240

Total Employee of Department C in year 2019
= Total employee in 2019 X Percentage of Employee of Department C in year 2019
= 20000 X 20%
= 20000 X 20 /100
= 4000

Formula:

Calculation:

Increase Percentage
= Total Employee of Department C in year 2019 – Total Employee of Department C in year 2018
= (4000 – 3240) X 100 / 3240
= 76000 / 3240
= 23.45 %

23.45 Percentage increase in the number of employees in the Department – C in the year 2019 with reference to the year 2018.

So, The correct Answer is Option (III).
