#### 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

#### 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).
