Question

A sold 2 horses at $2000 each.A made a profit of 20% on 1 and a loss of 10% on the other.Find out A's total profit or loss %.

Answer 1

Since he made a 20% profit on one, that horse's original price was 1.2x=2000 (solve for x).

The other horse's original price was .9y=2000

If x+y > 4000 (total sale price fo the two horses) then he made a profit. if less, he took a loss.

To find the %, divide the 4000 by x+y. If >1, subtract the 1 and the rest is the % (in decimal form). If <1, subtract *from* 1 and that is the % (in decimal form).
