Question : 135 of 200

Marks: +1, -0

Eighteen per cent of Country E’s total requirement of Iron ore is being met by imports from India. Next year, its total requirement of Iron ore is expected to fall by 22%, and only 12% of the revised requirement will be imported from India. Assuming all other exports to Country E by India remain at the same levels, what would be its total percentage drop in quantity of exports to E?

28.4
11.2
13.4

Solution:

18/100

= 32 tonnes
⇒ x = 177.77 tonnes
Requirement of Iron ore decreases by 22% in next year.
∴ E's Iron ore requirement in next year
= 177.77 x

78/100

= 138.66 tonnes
Total Iron ore imported from India to E after revised requirement = 138.66 x

12/100

= 16.63 tonnes
Total quantity of minerals before revision of requirement = 114 tonnes
Total quantity of minerals after revision of requirement = 16.63 + 29 + 48 + 2 + 3 = 98.63 tonnes
∴ Percentage drop in quantity of exports to E
=

{114-98.63}/114

x 100 = 13.4%
