## Introduction to Data Interpretation

#### Data Interpretation

Direction: Study the table carefully and answer the questions given below.

1. In which year the total production of scooters of all factories was 20% of the total production of scooters during 1985-1989?

1. On the basis of given table in question ,
Total production of scooters during 1985 - 1989 in thousands. = 115 + 108 + 149 + 102 + 101 = 575

 Now, 20% of 575 = 20 × 575 = 115 100

##### Correct Option: B

On the basis of given table in question ,
Total production of scooters during 1985 - 1989 in thousands. = 115 + 108 + 149 + 102 + 101 = 575

 Now, 20% of 575 = 20 × 575 = 115 100

It was in the year 1985.

1. In which year, the total production of scooters was maximum?

1. On the basis of given table in question ,
The total production of scooters in 1985 = 115
The total production of scooters in 1986 = 108
The total production of scooters in 1987 = 149
The total production of scooters in 1988 = 102
The total production of scooters in 1989 = 101

##### Correct Option: C

On the basis of given table in question ,
The total production of scooters in 1985 = 115
The total production of scooters in 1986 = 108
The total production of scooters in 1987 = 149
The total production of scooters in 1988 = 102
The total production of scooters in 1989 = 101
From above it is clear that it was maximum in the year 1987.

1. The ratio of the production of scooters by factory P to that by factory T in 1985 is

1. As per the given above table , we can see
The production of scooters by factory P in 1985 = 20
The production of scooters by factory T in 1985 = 40
Required ratio = The production of scooters by factory P in 1985 : The production of scooters by factory T in 1985

##### Correct Option: C

As per the given above table , we can see
The production of scooters by factory P in 1985 = 20
The production of scooters by factory T in 1985 = 40
Required ratio = The production of scooters by factory P in 1985 : The production of scooters by factory T in 1985

 Required ratio = 20 = 1 : 2 40

1. Which factory/factories showed a decrease of 25% in the production of scooters in 1989 as compared to 1988?

1. According to given table, we have
Company Q produced 20 thousands scooters in 1988 and 15 thousands in 1989. Clearly, a decrease of 25%. Similar is the case with company R also.

##### Correct Option: C

According to given table, we have
Company Q produced 20 thousands scooters in 1988 and 15 thousands in 1989. Clearly, a decrease of 25%. Similar is the case with company R also.
Thus , Q and R are required answer .

1. In which year, the production of scooters of all factories was equal to the yearly average number of scooters produced during 1985- 89?

1. As per the given above table , we can see
Total production of scooters of all factories = 115 + 108 + 149 + 102 + 101 = 575
Number of given years = 5

 Required Average = Total production of scooters of all factories Number of given years

##### Correct Option: A

As per the given above table , we can see
Total production of scooters of all factories = 115 + 108 + 149 + 102 + 101 = 575
Number of given years = 5

 Required Average = Total production of scooters of all factories Number of given years

 Required Average = 575 = 115 5

Clearly, it was in the year 1985.
