Introduction to Data Interpretation

Direction: The following table shows the worldwide production of steel in 1920–1927. Study the table and answer the questions.

  1. The difference of the production of steel in the year 1923 and 1924 is X% of 1927. Then the value of X is approximately
    1. 0.01
    2. 0.1
    3. 0.001
    4. 1
Correct Option: D

As per the given bar graph ,
The production of steel in the year 1924 = 77.23
and The production of steel in the year 1923 = 76.23
The production of steel in the year 1927 = 100.17
Difference of the production of steel in the year 1923 and 1924 = 77.23 - 76.23 = 1
According to the question,
X% of the production of steel in the year 1927 = Difference of the production of steel in the year 1923 and 1924

X × 100.17
= 1
100

X × 100.17
= 1
100

⇒ X =
100
≈ 1
100.7
