Question

in the following year, the value of imports to Greece decreased by 25%. If the value of Italian imports decreased by $750 million, what percentage of the following year's imports were from Italy?

Answer 1

Assuming the decrease is uniformly distributed over all countries, then the following  year's import from Italy is also 25%.

Next year's import
=750(1-25%)
=750(0.75)
=562.5 million (units).
