(A) 45 (B) 67 (C) 75 (D) 83 (E) 150 Let the smallest amount the original price of sweater be X So if we have 0.15*X>10 X> 10/0.15> 2/3*100= 66 Hence X is greater than 66. Smallest possible value will be 67. Ans B Difficulty level around 650 okay

Ans B
15/100 of x > 10
x>66.67 rounded off to 67.

15% of X = 10. X = 1000/15 = 66.67% ~ 67%, (B).

As a starting point, we can assume 15% of x = 10, where x is the price of sweater; Simplifying, we get x ~ 66.67.
Since Mel received a discount of more than 10%, the lowest price should at least be 66.67$ = 67$
Ans is B.

if 15 % are 10$ > 1% is 10/15 THAN 100% > 100*(10/15) = 66,7

I am seeing most of the solutions here were done with algebra. However, do you think it is just as efficient to think conceptually. Or did I happen to get lucky?
10% of 67 is 6.7
half of 6.7 is 3.35.
6.7+3.35 is 10.05.
is this an ok approach ?

is this an ok approach ? Absolutely Ok , no issues with your approach!! Infact QA questions can be solved by multiple approaches and it is good for test takers to explore alternate approaches and adopt the one with which they are confident to answer the question correctly. The main aim for any approach for tackling GMAT Question will be  1. Accuracy 2. Minimum Time Whichever approach you adopt doesn't matter. For the particular question IMHO Bunuels approach is the quickest and the best ( without unnecessarily involving in the complexity of handling decimal numbers) Undoubtedly U have a very good approach as well and this strategy really work well.. Keep practicing and finding out the strategy for tackling a particular problem with minimum time, the one that suits you  adopt it..

I think easiest approach is looking at the answers. By estimation, only b works. The others don't make sense. 20 seconds.

Discount will lead to saving, hence the original inequality will be 0.15*Price>10 Now coming to your question, what you have done here 0.85*Price>10 is that $10 saving is 85% more than the original price. Hence the question COULD be reworded as  "If Mel saved more than $10 by purchasing a sweater at 15 percent of its original price, what is the smallest amount the original price of the sweater could be, to the nearest dollar?"

The straightforward approach is to realize that we saved more than 10 dollars and the discount is 15% We look at the options. A) 45 and 10% equals 4.5 and 5% would be half of 4.5 so 2.25 + 4.5 = 6.75 less than 10 now B) 67,, 10% equals 6.7 and 5% equals 3.35 so 6.7 + 3.35 = 10.05 >10 and the smallest amount. Answer choice B.

A. 45 B. 67 C. 75 D. 83 E. 150 Let's calculate what happens if she saves exactly $10. Marked Price * (15/100) = 10 Marked Price = 200/3 = 66.67 The marked price must be greater than 66.67 since she saved more than $10. So the minimum amount of marked price = $67 Answer (B)

I have a question, I solved it by taking every value in the answer choice and multiplying it by 0.85 to see the difference. For example,
75 75*0.85> 10.
So the answer came to C as it has savings more than 10. B had savings equal to 10. Can someone explain me how to do it this way. Have I done it correct? But the answer I got is wrong...

Posted from my mobile device 67  67*0.85 = 10.05 > 10, so the smallest amount the original price of the sweater could be, to the nearest dollar is $67.
