#### Data Interpretation

Direction: The bar graph given below shows the spending of family income on various items and savings during 1993. Observe the graph and answer the following questions :

1. If the total income of the family during 1993 was \$ 100000, the savings of the family in 1993 was :

1. On the basis of given graph in question ,
The total income of the family during 1993 = \$ 100000
Percentage expenditure on Savings = 12.5%
Savings = 12.5% of \$ 100000

##### Correct Option: C

On the basis of given graph in question ,
The total income of the family during 1993 = \$ 100000
Percentage expenditure on Savings = 12.5%
Savings = 12.5% of \$ 100000

 Savings = \$ 12.5 × 100000 = \$ 12500 100

1. The percent of income spent on clothing exceeds that on savings by :

1. As per the given bar graph in question ,
Percentage expenditure on clothing = 15%
Percentage expenditure on savings = 12.5%
∴ Required difference = Percentage expenditure on clothing - Percentage expenditure on savings

##### Correct Option: B

As per the given bar graph in question ,
Percentage expenditure on clothing = 15%
Percentage expenditure on savings = 12.5%
∴ Required difference = Percentage expenditure on clothing - Percentage expenditure on savings
∴ Required difference = (15 – 12.5)% = 2.5%

1. The percent of income spent on food is :

1. According to given graph in question ,
The percent of income spend on food is 20%.

##### Correct Option: D

According to given graph in question ,
The percent of income spend on food is 20%. Hence , option D is correct answer .

Direction: Study the following line chart carefully and answer the questions given below it. The following line chart represents the number of employees recruited in different years in a company.

1. The number of employees recruited in 2015 was 40% more than that recruited in 2014. How many employees were recruited in 2015?

1. According to given graph in question ,
The number of employees recruited in 2014 = 40
The number of employees recruited in 2015 = 140% of 40

 Employees recruited in 2015 = 40 × 140 100

##### Correct Option: A

According to given graph in question ,
The number of employees recruited in 2014 = 40
The number of employees recruited in 2015 = 140% of 40

 Employees recruited in 2015 = 40 × 140 = 56 100

1. If the number of employees before 2010 was 640, what was percentage increase in 2010?

1. On the basis of given graph in question ,
The number of employees before 2010 = 640
The number of employees in 2010 = 35

 Percentage increase = The number of employees in 2010 × 100 The number of employees before 2010

##### Correct Option: B

On the basis of given graph in question ,
The number of employees before 2010 = 640
The number of employees in 2010 = 35

 Percentage increase = The number of employees in 2010 × 100 The number of employees before 2010

 Percentage increase = 35 × 100 ≈ 5.5 640
