(B) Loss of $2,500 (C) Gain of$1,250
(D) Gain of $2,500 (E) Neither a net gain nor a net loss Since the selling price of$30,000 is 20% more than the cost price of X, the selling price of $30,000 is equal to 120% of the cost price of X: 30,000 = (120/100)X 30,000 = (6/5)X (5/6)(30,000) = X X = 25,000. Since the selling price of$30,000 is 20% less than the cost price of Y, the selling price of $30,000 is equal to 80% of the cost price of Y: 30,000 = (80/100)Y 30,000 = (4/5)Y (5/4)(30,000) = Y Y = 37,500. Sum of the cost prices = 25,000 + 37,500 = 62,500. Sum of the selling prices = 30,000 + 30,000 = 60,000. Net loss = (sum of the cost prices) - (sum of the selling prices) = 62,500 - 60,000 = 2500. The correct answer is B. _________________ Mitch Hunt GMAT Private Tutor GMATGuruNY@gmail.com If you find one of my posts helpful, please take a moment to click on the "Thank" icon.

Hi Roland2rule,
Lets take a look at your question.

Let the property X has original value of $x, then, it sale price i.e.$30,000 at 20% profit can be represented as:
$$x\ +\ \left(20\%\right)x=30,000$$
$$x\ +\ \left(\frac{20}{100}\right)x=30,000$$
$$x\ +\ \left(0.2\right)x=30,000$$
$$1.2x=30,000$$
$$x=\frac{30,000}{1.2}$$
$$x=25,000$$

Therefore, original price of property X is $25,000 and it was sold at$30,000.
Profit Gained = $30,000 -$25,000 = $5,000 Let the property Y has original value of$y, then, it sale price i.e. $30,000 at 20% loss can be represented as: $$y\ -\ \left(20\%\right)y=30,000$$ $$y\ -\ \left(\frac{20}{100}\right)y=30,000$$ $$y\ -\ \left(0.2\right)x=30,000$$ $$0.8x=30,000$$ $$x=\frac{30,000}{0.8}$$ $$x=37,500$$ Therefore, original price of property Y is$37,500 and it was sold at $30,000. Loss =$37,500 - $30,000 =$7,500

There is a gain of $5,000 in property X and loss of$7,500 in property Y.
The loss is greater than the profit, so to find the total loss we will subtract the profit from the loss.

Loss = 7,500 - 5,000 = \$2,500

Therefore, Option B is correct.
Hope this helps.
