The given table represents the exports (in ₹crores) of four items A, B, C and D over a period of six years. Study the table and answer the question that follows.

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)

14.3%

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%
