There are six types of employees working in an organization. The pie chart given below shows the different types of employees working in the organization in the year 2017.

Important for :
1
In the year 2017, total number of 500 employees was working in the organization. In the year 2018, 50 more joined the organization out of which 20 was F type employees then in the year 2018, total number of F type employees was what percentage of the total number of employees? (rounded off two decimal)
» Explain it
D
First covert the given pie chart in the term of percentage

For type A employee, 360 = 100%

 43.2 = 100 × 43.2 = 12% 360

 Types Percentage A (100 × 43.2)/360 = 12% B (100 × 64.8)/360 = 18% C (100 × 115.2)/360 = 32% D (100 × 28.8)/360 = 8% E (100 × 57.6)/360 = 16% F (100 × 50.4)/360 = 14%

Total number of employees in the year 2017 = 500

The total number of F types employees in the year 2017 = 14% of 500 = 70

Total number of employees in the year 2018 = 500 + 50 = 550

Total number of F type employees in the year 2018 = 70 + 20 = 90

 The reqd. % = 90 × 100 = 16.37% 550

Hence, option D is correct.
2
In the year 2017, the difference between B type employees and D type employees was 40, then find the total number of F type employees working in the organization?
» Explain it
C
 Types Percentage A 12% B 18% C 32% D 8% E 16% F 14%

In the year 2017, let the total number of employees = 100x

Then, according to the question 18% of 100x – 8% of 100x = 10% of 100x = 10x = 40

X = 4

Therefore, the number of employees in the year 2017 = 100 × 4 = 400

The number of F type employees = 14% of 400

 = 14 × 400 = 56 100

Hence, option C is correct.
3
In the year 2017, the number of D type employees was what percent less than the number of A type employees?
» Explain it
B
 Types Percentage A 12% B 18% C 32% D 8% E 16% F 14%

Let the total number of employees = 100x

D type employees = 8% of 100x = 8x

A type employee = 12% of 100x = 12x

 The reqd. % = (12x – 8x) × 100 = 100 = 33.33% 12x 3

Hence, option B is correct.
4
In the year 2018, the ratio of the number of B type employees to the number of E type employees was 11: 9 then what is the total percentage increase in the number of B type employee and E type employees together?
» Explain it
E
 Types Percentage A 12% B 18% C 32% D 8% E 16% F 14%

Let the total number of employees = 100x

B type employees = 18% of 100x = 18x

E type employee = 16% of 100x = 16x

The ratio = 18x : 16x = 9 : 8

In the year 2018, the ratio becomes 11 : 9

Except ratio, we don’t have any information about the number of employees in 2018 therefore answer can’t be determined.

Hence, option E is correct.
5
In the year 2017, the difference between C type employees and F type employees was 126 then in that year what was the difference between F type employees and D type employees?
» Explain it
C
Let the total number of employees = 100x

C type employees = 32% of 100x = 32x

F type employees = 14% of 100x = 14x

According to the question, 32x – 14x = 18x = 126, x = 7

The required difference = 14% of 100x – 8% of 100x = 6x = 42

Hence, option C is correct.
