Profit made per item = 160
Let last number of unsold items be Y

So profit on the last item will be (160 -X)Y > 60

This gives 160Y - XY > 60

From the relationship, find largest value of X that can accommodate Y to make the equation true.
Answer is 50 and 75.

(560-x)/400 > 1.15 (since a 15% profit would mean it sold for 115% of cost)
560-x>460
-x>100
x<100 --> A and B only
