Is there a loss in transaction?
1) 20% of Cost price is $20 more than 40% of selling price.
So \(\frac{20}{100}*C=20+S*\frac{40}{100}.....20C=2000+40S...C=100+2S\)
So Cost Price is more than Selling price
Therefore loss
Sufficient
2) 30% of Cost price is $10 less than 20% of selling price.
So \(\frac{30}{100}*C=S*\frac{20}{100}-10.....30C=20S-1000.........\)
So Cost Price is less than Selling price
Therefore profit
Sufficient
D..
Note.. you can't have two different answers from the two statements, so question is flaqed
