from statement (1), the percent increase can be directlycalculated:
\(\frac{{800,000 - 600,000}}{{600,000}} * 100\) = 33.33% -->sufficient
from statement (2), let the revenues in 1980 =\(x\) , so revenues in 1985 =\(x + (5*40,000)\) .
so the percentage =\(\frac{{x + 200,000 - x}}{{x}} *100\) =\(\frac{200,000}{x}*100\) --> since x is unknown, soinsufficient
so A
