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 D in 2010, 2012 and 2014 is what percentage of the total exports of all the four items in 2011 and 2012 ?

44%

Total export of D in 2010 , 2012 & 2014 = 214 + 247 + 309 = 770

Total export of all in 2011 & 2012 = ( 250 + 134 + 244 + 282 ) + ( 225 + 138 + 230 + 247 )

= 910 + 840

= 1750

Required percentage = \(\frac{770 }{1750}\) × 100

= 44%
