The table below embodies data on the oil import (in million tonnes) from six different countries over the years 2015 to 2019. In accordance with the table, answer the questions
If P and Q are the average oil import from all the countries in the year 2019 and 2017 respectively, then P-Q is approximately equal to :
- A.
3.43 million tonnes
- B.
3.34 million tonnes
- C.
2.43 million tonnes
- D.
2.34 million tonnes
Show answer & explanation
Correct answer: A
From the table, total oil import in 2019 = 32.6 + 17.5 + 24.6 + 14.2 + 17.8 + 9.6 = 116.3 million tonnes.
So, P = average import in 2019 = 116.3/6 = 19.38 million tonnes approximately.
Total oil import in 2017 = 27.2 + 21.2 + 15.0 + 13.2 + 11.8 + 7.3 = 95.7 million tonnes.
So, Q = average import in 2017 = 95.7/6 = 15.95 million tonnes.
Therefore, P - Q = 19.38 - 15.95 = 3.43 million tonnes approximately.
Hence, the correct answer is 3.43 million tonnes.
