## Introduction to Data Interpretation

#### Data Interpretation

Direction: Study the following table and answer the questions given below. 1. For school E, what percent of the income from miscellaneous is the income from the donation?

1. On the basis of given table in question ,
The income from miscellaneous = 15 thousands
The income from the donation = 60 thousands

 Required percentage = The income from the donation × 100 % The income from miscellaneous

##### Correct Option: D

On the basis of given table in question ,
The income from miscellaneous = 15 thousands
The income from the donation = 60 thousands

 Required percentage = The income from the donation × 100 % The income from miscellaneous

 Required percentage = 60 × 100 = 400% 15

Direction: The following questions are based on the table given below which represents the distance (in km) travelled by two persons A and B in the same direction : 1. The distance between A and B is maximum at the end of

1. As per the given above table , we see
Distance after 2 hours = 65 – 50 = 15 km
Distance after 3 hours = 100 – 70 = 30 km
Distance after 4 hours = 125 – 85 = 40 km

##### Correct Option: D

As per the given above table , we see
Distance after 2 hours = 65 – 50 = 15 km
Distance after 3 hours = 100 – 70 = 30 km
Distance after 4 hours = 125 – 85 = 40 km
Distance after 5 hours =160 – 110 = 50 km (maximum distance)
Thus , required answer is 5 hours .

1. What is the distance (in km) between A and B at the end of 8th hour?

1. According to given table, we have
Total distance travelled in first eight hours by B = 25 + 40 + 35 + 25 + 35 + 10 + 25 + 15 = 210 kms
Total distance travelled in first eight hours by A = 20 + 30 + 20 + 15 + 25 + 15 + 25 + 35 = 185 kms
∴ Required distance = Total distance travelled in first eight hours by B - Total distance travelled in first eight hours by A

##### Correct Option: B

According to given table, we have
Total distance travelled in first eight hours by B = 25 + 40 + 35 + 25 + 35 + 10 + 25 + 15 = 210 kms
Total distance travelled in first eight hours by A = 20 + 30 + 20 + 15 + 25 + 15 + 25 + 35 = 185 kms
∴ Required distance = Total distance travelled in first eight hours by B - Total distance travelled in first eight hours by A
Required distance = 210 – 185 = 25 km

1. The ratio of A’s speed during the first five hours and the last five hours is

1. From the given above table ,
Total distance travelled in first five hours by A = 20 + 30 + 20 + 15 + 25 = 110 kms
Total time taken = 5 hours
Total distance travelled in last five hours by A = 15 + 25 + 35 + 20 + 30 = 125 kms
Total time taken = 5 hours

 Required ratio = Total distance travelled in first five hours by A : Total distance travelled in last five hours by A Total time taken Total time taken

##### Correct Option: B

From the given above table ,
Total distance travelled in first five hours by A = 20 + 30 + 20 + 15 + 25 = 110 kms
Total time taken = 5 hours
Total distance travelled in last five hours by A = 15 + 25 + 35 + 20 + 30 = 125 kms
Total time taken = 5 hours

 Required ratio = Total distance travelled in first five hours by A : Total distance travelled in last five hours by A Total time taken Total time taken

 Required ratio of average speed = 110 : 125 = 110 : 125 = 22 : 25 5 5

1. B’s average speed (km/hour) during the first four hours is

1. On the basis of given table in question ,
Total distance travelled in first four hours by B = 25 + 40 + 35 + 25 = 125 kms
Total time taken = 4 hours

 B’s average speed = Total distance travelled in first four hours by B kmph Total time taken

##### Correct Option: C

On the basis of given table in question ,
Total distance travelled in first four hours by B = 25 + 40 + 35 + 25 = 125 kms
Total time taken = 4 hours

 B’s average speed = Total distance travelled in first four hours by B kmph Total time taken

 B’s average speed = 25 + 40 + 35 + 25 kmph = 31.25 kmph 4
