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

1) 20/100∗C=20+S∗40/100
C=100+2S
Sufficient

2)30/100∗C=S∗20/100−10
30C+1000=20S
1.5C+50=S
Sufficient

Hence D

Dear Moderator,
Can we mark this question as poor quality as we seem to be getting two different answers from the two statements. Thank you.
