In which year was the largest combined change in supply from the previous year for OPEC, the former USSR and other Non-OECD countries?

(i) Percentage increase in the price of oil between 1998 and 2006.

In 1998 it was 12.7 and in 2006 it was 65.1

so equation is 12.7*x = 65.1 which is x=5.1259% or 5.13%(round figure).

Hence, (5.) 5.13% is the answer.

(ii) If the total oil supply had grown at the same rate as the former USSR oil supply between 2000 and 2006 how much would this have exceeded the demand in 2006?

rate of growth of former USSR oil supply between 2000 and 2006

In 2000 it was 7.9 and in 2006 it was 12.2

so the equation is 7.9*x = 12.2 which is 1.544%

According to question total oil suppy had grown @ the same rate i.e 1.544%

total oil supply in 2000 is 77.1

so the after growth 77.1 * 1.544 = 119.0424

Now, According to the question : how much would this have exceeded the demand in 2006?

Total Demand in 2006 is 84.7

Difference is 119.0424 - 84.7 = 34.3424

Hence (5.) 34.3 is the answer.

(iii) In which year was the largest combined change in supply from the previous year for OPEC, the former USSR and other Non-OECD countries?
