How much does a sweater cost that is 18% more than a $50 dress?
Tap to reveal answer
18% of the dress is .18 * 50 = $9. Then the sweater costs $50 + $9 = $59.
18% of the dress is .18 * 50 = $9. Then the sweater costs $50 + $9 = $59.

There are two ways to consider the value of B. First, you can subtract 40% from the initial $50 dollars: $50 – 0.4 * $50 = $30. This gives you the value after the markdown. Then to mark up the price, add 50% of $30 to the $30: $30 + 0.5 * $30 = $45.
A shorter way to do this problem is to consider the first markdown as reducing the price to 60% of the original, then considering the markup as making it 150% of the new price. This can be done in one set of multiplications: $50 * 0.6 * 1.5 = $45. Either way, the answer is the same. A is the larger quantity.

Tap to reveal answer
To solve this problem, imagine that the original price of the laptop is $100. After the first 20% discount, the price of the laptop becomes $80. With the additional 10% reduction, we discount from $80, not $100. 10% of 80 is 8 so we must deduct $8 from $80. This gives $72 as the final price of the laptop after both reductions. Since we started at $100, the total discount is 28%.

A store puts a $200 dress on a 70% discount and then takes an additional 15% off the reduced price. How much of the original price was removed?
Tap to reveal answer
If we multiply $200 by 0.7, we find the dress has been reduced by $140 on the first discount. Since the dress now costs $60, we multiply that by 0.15 and find the dress has been discounted by an additional $9. The final sale of the dress is $51, with $149 of the original price removed.

Normally, 3 pens cost 3 * .49 = $1.47. Thus, on each set of 3 pens, the sale price saves the customer $1.47 - 99 = 48 cents. Multiply this by 4 to get the savings for 12 pens, and you get .48 * 4 = $1.92.

This is a straightforward percentage problem. After the first discount, the price of the weights is $0.8X. This price is then further reduced by 10% for the employee discount. 90% of 0.8X = 0.9(0.8X) = 0.72X.

The easiest way to solve this is to note that a 30% markdown reduces the cost to 70% of the original cost. Likewise, a 40% markup is the same as making the price 140% of its current value. Using this, we can solve our problem in one string of multiplications:
New cost = Original * 0.7 * 1.4 * 0.9
New cost = 20 * 0.7 * 1.4 * 0.9 = 17.64

A dress originally costs $50 but is on sale for 25% off. In addition, you have a 10% off coupon. How much will the dress cost after these discounts?
Tap to reveal answer
To find 25% of $50 you multiply 50 and 0.25. This gives you 12.50. This means the dress is $12.50 cheaper, so it now costs 50 – 12.50 = $37.50. You have an additional 10% off, so you multiply 37.50 by 0.10 to get 3.75. 37.50 – 3.75 = $33.75. This is the cost of the dress. NOTE: You CANNOT add 25% and 10% and take 35% off of the $50 dress. You will get the wrong answer.

Let's begin by finding the absolute amount necessary for a 27% profit. Following that, we will adjust for the needs of having a whole number price. If the sale price is S, we can set up the following equation:
(S – 23)/23 = 0.27
S – 23 = 6.21
S = 29.21
The product must, however, be sold for at least $30 because it has to be an integer value.

To calculate a 30% increase in cost, you can multiply the base cost by 1.3; therefore, if we are going to increase the rate five times, we will multiply by 1.3 five times, which is the same as 1.35. The cost of creating 100 units per hour is 27 * 1.35 = 100.25.
If we want to make a 25% profit, we can set up the equation:
Price = 1.25 * 100.25 or 125.3125. To make at least a 25%, this will be $125.32.

The sweater price starts at $36. Alice pays $36 – (.25 * $36) = $27. Chelsea then pays $27 – (.15 * $27) = $22.95, which is the correct answer.
When solving percentage questions such as this one, do NOT try to add up the discounts and find the final sale price all in one step. If you tried to do that here, the answer would have been $36 – (.25 + .15) * $36 = $21.60. This is an answer choice, but the wrong answer! Most GRE percentage questions will always give you this as one of your answer choices to try and trick you!

There are two ways to consider the value of B. First, you can subtract 40% from the initial $50 dollars: $50 – 0.4 * $50 = $30. This gives you the value after the markdown. Then to mark up the price, add 50% of $30 to the $30: $30 + 0.5 * $30 = $45.
A shorter way to do this problem is to consider the first markdown as reducing the price to 60% of the original, then considering the markup as making it 150% of the new price. This can be done in one set of multiplications: $50 * 0.6 * 1.5 = $45. Either way, the answer is the same. A is the larger quantity.
