I have a question. What perform you think it's the a lot of efficient/fast method to resolve difficulties like this:

The list price of a certain tool is x dollars. In Store A the original selling price of the tool was $50 less than the list price, and the present offering price is 10 percent less than the original selling price. In Store B the original selling price of the tool was 10 percent much less than the list price, and the existing marketing price is $50 much less than the original selling price.

You are watching: The list price of a certain tool is x dollars

A: current price of item in store A

B: present price of item in save B

Do you review the entire trouble first and also attempt to settle it? If so a lot of time is being wasted and you may not gain all the details, is this a difficulty for you? it is for me?

Do you compose details as you review the problem without looking at the question? or do you look at the question first?

I am simply trying to discover the fastest means to settle this one properly. These are the ones that take me the most time.

I'm not certain if this is the ideal method yet I would certainly initially glance at the question and see it was wordy, then glance dvery own at the multiple alternative answers to see what I was searching for, following go with the trouble jotting it down in regards to an equation. Something like

A**original** = x-50

A**current** = 0.9(A**original**) = 0.9(x-50)

B**original** = 0.9x

B**current** = B**original** - 50 = 0.9x-50

edit: So currently I would say that A would certainly have to be better because 90% of something minus 90% of 50 has obtained to be larger than 90% of something minus the whole 50.

This appears reliable to me yet there could be better means also. How carry out you execute it?

Many GRE research books have actually tactics for these. In this case, you make a table as quickly as you see all these measures and problems. (Can't draw it out in here, yet most GRE research publications will certainly have actually plenty of examples. Each column is an additional adjust in price sort of thing, with the answers as rows so you can plug in and also test them.) So you take notes in the table as you read it. Keeps it arranged and also fast.

As you are reading the difficulty, compose dvery own the crucial points on your sheet, simply enough to consolidate the information. Sometimes the problem statement can be convoluted, and also you might have to read it several time.

For this trouble, you deserve to watch my video explacountry to view exactly how I would do it in an exam setting: http://www.quantumgradprep.com/gre-powerprep-online-test-1/question-01-section-5-hard-gre-powerprep-online-test-1-quant.html

In my opinion, there's no factor to use algebra in this question. You deserve to, especially if you're extremely good at algebra, but it's time consuming to erected.

I would certainly initially read the difficulty and understand also what the hell is going on. Then number out the most efficient way to resolve the trouble.

The question offers you no limitations which indicates you have the right to usage any number. The simplest number to usage for a question like this is $100. If you follow the directions, you acquire the amount a is 45.

$100 (original price) - $50= $50. Then take 10% away giving you 45.

B claims 10% off of $100 or 90, and then take away $50 you obtain $40 left.

What's bigger? 45>40 therefore your answer is A.

If you try to analyze all those words right into algebra it's a pain. If you use genuine numbers, and have a solid arithmetic structure this becomes a basic plug and chug trouble.
