Solution:

(d) Total demand of Coal after increase in demand by 12% = 149 x

112/100

= 166.88 tonnes
Total demand of Iron ore after increase in demand by 8% = 103 x

108/100

= 111.24 tonnes
Total demand of Copper after increase in demand by 15% = 75 x

115/100

= 86.25 tonnes
Total export of minerals after inc rease in demand = 166.88 + 111.24 + 86.25 + 132 + 28
= 524.37 ≈ 524 tonnes
Increase in percentage =
