The total exports of item A from 2012 to 2014 is what percentage less than the total exports ofall the four items in 2015? (Correct to one decimal place)
Answer & explanation
Correct answer: option 3
Total export of A from 2012 to 2014 = 225 + 370 + 425 = 1020
Total export of all items in 2015 = 400 + 209 + 306 + 275 = 1190
Required percentage = \(\frac{1190 - 1020}{1190}\) × 100
= \(\frac{170}{1190}\) × 100
= 14.3%
