Let n be total number if sweaters sold during the season

Revenue per sweater = >Selling Price per 1 sweater(SP) - Cost Price per sweater(CP) = Total revenue/n

from st 1 SP- CP = 270/n
But SP = CP + 30 (fron the question)
CP+30- CP = 270/n
Solving n = 9

Sufficient


From st 2,
SP = (150/100)CP
No sufficient info to find the number of Sweaters

So IMO A

I think you are right Scoobydooby ....good that I learnt it here ...not at the real GMAT test ... :D
Don't want to experience this in GMAT....Experience is the best teacher but she sends in terrific bills :shock:


statement 1 nSP = 270

Statement 2 SP = 150/100 CP
CP +30 = 3/2 CP
CP = 60
Then SP = 60 + 30 = 90

from st 1 90n = 270
n= 3

IMO C
