How many items did BOb produce
Source: Beat The GMAT — Data Sufficiency |
Well, this is a tricky question:
Statement 1: Insufficient
Statement 2: Insufficient
Combine:
Ammount expend last week 480$
Ammount expend this week 510$ (Two more units)
So 510-480=30$ Each unit is $15
If you divide 510/15 = 34 units
If you divide 480/15 = 32 units
So you could have produced 32 units last week, but 15$ could also be the price of 1.5(x) and in this case x would be $10. If you plugged some numbers you will note that you could have produced 36 units @ $10 + 8 more units @ $15 and get a total of $480. So in this case your total units produced would be 44 or 46...
Hence E
