Solution:

(d) After increment, international demand of Coal
= 112% of149 = 166 88 thousand tonnes
Iron ore = 108% of 103 = 111.24 thousand tonnes
Copper = 115% of 75 = 86.25 thousand tonnes
Therefore, after increment total quantity of minerals exported from India
= 166.88+ 111.24 + 86.25 + 132 + 28= 524.37 thousand tonnes
Thus, required percentage increase
=

{524 .37 - 487}/487

x100 %
=

37.37/487

x 100% = 7.6%
