In which year, the exports of item D were 1.4 times the average exports of item B during six years?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e 2013
We could check each year one by one or we could try a trick.
The export of year D was 1.4 times which is 0.2 × 7, we can divide the export of D of each year to eliminate the options.
The only year 2013 completely divided by 1.4 which is our answer.
