**Instructions**

The two plots below show data for four companies code-named A, B, C, and D over three years – 2019, 2020, and 2021.

The first plot shows the revenues and costs incurred by the companies during these years.Â For example, in 2021, company C earned Rs.100 crores in revenue and spent Rs.30 crores.Â The profit of a company is defined as its revenue minus its costs

The second plot shows the number of employees employed by the company (employee strength) at the start of each of these three years, as well as the number of new employees hired each year (new hires). For example, Company B had 250 employees at the start of 2021, and 30 new employees joined the company during the year.

**Question 1:Â **Profit per employee is the ratio of a company’s profit to its employee strength. For this purpose, the employee strength in a year is the average of the employee strength at the beginning of that year and the beginning of the next year. In 2020, which of the four companies had the highest profit per employee?

a)Â Company D

b)Â Company C

c)Â Company B

d)Â Company A

**1)Â AnswerÂ (C)**

**Solution:**

It is given,

Company A =Â $\frac{90-65}{145}=\frac{25}{145}=\frac{50}{290}$

Company B =Â $\frac{90-40}{245}=\frac{50}{245}$

Company C =Â $\frac{70-60}{320}=\frac{10}{320}$

Company BÂ had the highest profit per employee.

The answer is option C.

**Question 2:Â **The total number of employees lost in 2019 and 2020 was the least for:

a)Â Company B

b)Â Company D

c)Â Company A

d)Â Company C

**2)Â AnswerÂ (A)**

**Solution:**

It is given,

Company A:

The number of employees in the beginning of 2019 = 150

The number of employees hired in 2019 = 20

The number of employees should be at the beginning of 2020 is 150+20, i.e. 170 but there are 140 only. This implies 30 left company A in 2019.

The number of employees in the beginning of 2020 = 140

The number of employees hired in 2020 = 35

The number of employees should be at the beginning of 2021 is 140+35, i.e. 175 but there are 150 only. This implies 25 left company A in 2020.

The number of employees left company A in 2019 and 2020 = 30 + 25 = 55

Company B:

Similarly, the number of employees left company B in 2019 = 210 + 35 – 240 = 5

The number of employees left company B in 2020 = 240 + 45 – 250 = 35

The number of employees left company B in 2019 and 2020 = 5 + 35 = 40

Company C:

Similarly, the number of employees left company C in 2019 = 320 + 45 – 320 = 45

The number of employees left company C in 2020 = 320 + 40 – 320 = 40

The number of employees left company C in 2019 and 2020 = 45 + 40 = 85

Company D:

Similarly, the number of employees left company D in 2019 = 400 + 30 – 410 = 20

The number of employees left company D in 2020 = 410 + 35 – 400 = 45

The number of employees left company D in 2019 and 2020 = 20 + 45 = 65

The total number of employees lost in 2019 and 2020 is least for company B.

The answer is option A.

**Question 3:Â **The ratio of a company’s annual profit to its annual costs is a measure of its performance. Which of the four companies had the lowest value of this ratio in 2019?

a)Â Company A

b)Â Company D

c)Â Company B

d)Â Company C

**3)Â AnswerÂ (A)**

**Solution:**

It is given,

Measure of A’s performance in 2019 =Â $\frac{90-85}{85}=\frac{5}{85}=0.06$

Measure of B’s performance in 2019 = $\frac{100-75}{75}=\frac{25}{75}=0.33$

Measure of C’s performance in 2019 = $\frac{25-20}{25}=\frac{5}{25}=0.2$

Measure of D’s performance in 2019 = $\frac{50-40}{40}=\frac{10}{40}=0.25$

Company AÂ had the lowest value.

The answer is option A.

**Instructions**

A large store has only three departments, Clothing, Produce, and Electronics. The following figure shows the percentages of revenue and cost from the three departments for the years 2016, 2017 and 2018. The dotted lines depict percentage levels. So for example, in 2016, 50% of store’s revenue came from its Electronics department while 40% of its costs were incurred in the Produce department.

In this setup, Profit is computed as (Revenue – Cost) and Percentage Profit as Profit/Cost Ã— 100%.

It is known that

1. The percentage profit for the store in 2016 was 100%.

2. The storeâ€™s revenue doubled from 2016 to 2017, and its cost doubled from 2016 to 2018.

3. There was no profit from the Electronics department in 2017.

4. In 2018, the revenue from the Clothing department was the same as the cost incurred in the Produce department.

**Question 10:Â **What was the approximate difference in profit percentages of the store in 2017 and 2018?

a)Â 15.5

b)Â 25.0

c)Â 8.3

d)Â 33.3

**10)Â AnswerÂ (C)**

**Solution:**

We can make the following table from the web chart given in the question:

If we consider the total cost in the year

2016 as 100, then according to Statement 1, the total revenue in 2016 must be 200.

The storeâ€™s revenue doubled from 2016 to 2017, thus the total revenue in the year 2017 = 400.

We can find the revenue for the individual department in the year 2017, from the table.

There was no profit from the Electronics department in 2017, thus, we can find the total cost in 2017= 300

Considering the statement 4, we can find the total revenue in 2018 and tabulate the following table.

Profit percentage in 2017= (400-300)/300 %= 33.33%

Profit percentage in 2018= (250-200)/200 %= 25%

The approximate difference in profit percentages of the store in 2017 and 2018= (33.33-25)%= 8.33%

Option C.

**Question 11:Â **What percentage of the total profits for the store in 2016 was from the Electronics department?

**11)Â Answer:Â 70**

**Solution:**

We can make the following table from the web chart given in the question:

If we consider the total cost in the year

2016 as 100, then according to Statement 1, the total revenue in 2016 must be 200.

The storeâ€™s revenue doubled from 2016 to 2017, thus the total revenue in the year 2017 = 400.

We can find the revenue for the individual department in the year 2017, from the table.

There was no profit from the Electronics department in 2017, thus, we can find the total cost in 2017= 300

Considering the statement 4, we can find the total revenue in 2018 and tabulate the following table.

Profit in 2016 = 200-100= 100

Profit in the electronic department in 2016= 100-30=70

The total profits= for the store in 2016 were from the Electronics department 70%

**Question 12:Â **What was the ratio of revenue generated from the Produce department in 2017 to that in 2018?

a)Â 16 : 9

b)Â 4 : 3

c)Â 9 : 16

d)Â 8 : 5

**12)Â AnswerÂ (D)**

**Solution:**
