Solution:

(d) After hike in prices the quantity of export of different minerals are as follows.
Iron ore = 103 x

106/100

= 109.18 tonnes
Gold = 28 x

88/100

= 24.64 tonnes
Silver = 132 x

86/100

= 113.52 tonnes
Coal = 149 tonnes
Copper = 75 tonnes
∴ Total export of minerals after rise in prices
= 109.18 + 24.64 + 113.52 + 149 + 75 = 471.34 tonnes
Total export of minerals before rise in prices = 487 tonnes
Net effect on volume of exports
=

{487 - 471.34}/487

x 100 = 3.2%
∴ Decrease in volume of exports by 3.2%.
