the answer is C
answer is D.s
This cannot be determined. Each store might have had a different retail amount in 1977.
i think E is right
the ans is e
i think it's q
i think it's q
ans is E as initial sale volume of the given items are not given.
q
q
i tink its q
Why would it be Q?
E is my guess.
hey give the answer ..as we cannot go on expecting an option to be true
Answer is "E"
as data given is %age change....
not actual sales..
Answer is E as data is given in percentage not in actual number
Answer is E because the problem is not giving sales, so the dollar amount depend of the sales
its q coz da % change is given.... & q had the worst % sale in 1978 from there it has gone to +9% in 1979 so the diff is the greatest compared to others....
its q coz in 1977-1978 he had worst sale. but during 1978-1979 he got rise more than other who rise in sale. so q got more rise than any other.
i believe its R... you multiply the percentages across the 2 years for each store, to get the total percentage change per store. it doesn't matter what the actual $ value is to start with as we're dealing with percentage...
The data given are %change. We have no information about the absolute quantities, just the relative differences.
The question is about absolute quantities => Can't be determined.
Let's say P sold 10.000$ in 1977, we can find the mount sold in 1979 easily:
10.000*(1+10/100)*(1-10/100)
An so on eith each one of the companies.
The problem is we have no initial amount, no 10.000$ or whatever so we can't do any calculatons
ANSWER is E
EEEEEEEEEEEEEEEEEEEEEEEEEe
