It's asking if the last real overseas revenue will be more than 30% of the consolidated revenue after taking errors between the real and estimated values into account.
1. Estimated at 40%
This is all fine and dandy but it doesn't tell us anything about the difference between estimated and real. It could be estimated at 40% but be off by 20% or something
2. The estimated error is less than 10%
on it's own this doesn't tell us anything because we don't know what the estimation is. it could be 20% off by 10 or 90% off by 10
but when we take them together we know the estimate is 40% and the error is <10% so the real value must be between 40 +/- 10% or more than 30% and less than 50%.
since this range is all more than 30% you have your answer.
C it is.
