A shopkeeper sells one pen for 99 cents and makes 10% percent profit. He sells another pen for 99 cents and makes 10% loss. If he sells one pen of each type, would he make a profit, loss or break even?

The first pen originally cost 90 cents. 10% of 90 = 9 so he sells it for 99 cents and makes 9 cents,
The second pen originally cost $1.10. 10% of 1.10 = 11 cents so he sells it for an 11 cent loss.
If he sells one pen of each type he makes a loss of 2 cents.
