Hello All GMAT experts,

GMATNinja, bb, Bunuel and all others.

I have a question:

How to increase profit while the sales price stays the same but the cost price goes down?

I have been experimenting with this idea for quit a while and still can not figure out a way to do it.
Maybe my brain is exhausted.
I also searched the GMAT club Quantitative Forum for a couple of night by now to find some, close, examples but have be unsuccessful.

I really need your help and examples if possible.

Respect

Hi Heseraj,

By definition, "profit" is the DIFFERENCE between the 'cost' of an item and the 'sell price' of the item. For example, if an item costs you \$10 and you sell it for \$12, then the profit is...

(Sell price) - (cost) = \$12 - \$10 = \$2 of profit

Since there are two 'pieces' to this equation, you can increase the profit on an item by EITHER raising the sell price OR lowering your initial cost.

In this example, if you increase the sell price to \$13, then you can increase the profit...

\$13 - \$10 = \$3 of profit

You could achieve the same level of profit if you could decrease the initial cost (if the initial cost was just \$9 instead of \$10)....

\$12 - \$9 = \$3 of profit

Beyond the sale of one item, you can also increase OVERALL profit by increasing the number of items sold (at a given profit margin).

Thank you very much for the response. It is very helpful.

However, i was searching within GMAT club to find examples such as the one below:

The sales price has a 10 percent over the cost price. However, after a 10 percent reduction in the cost price, the same sales price of (11/10x) would translate to 20 percent profit. Now if the reduced cost price is equal to 200, what is the sales price?

Can you kindly please provide me an example such as this from GMAT club questions forum, something that i failed to do during last two weeks, so i can digest the concept.

Hi Heseraj,

Assuming that you've transcribed this question correctly, there's something "off" about the math in this question. Here's why:

We're told that the sale price is 10% above the cost price. For example...

Cost price = \$100
Sale price = \$110

The prompt then tells us that there is a 10% drop in the cost price, so we now have....

Cost price = \$90
Sale price = \$110

However, at this point, that same Sale price is NOT 20% greater than the Cost price; it's 20/90 = 2/9 = 22.222222% greater than the cost price. This result occurs regardless of the numbers that you use. Thus, there's something wrong with the example that you're listing.

All of that having been said, this question is really just about Percentage Change (and you should be able to search for that concept).

Rich
