Help with Quantitative Question on Selling Price

Hello, 

Does anyone please have any tips on how to solve this problem:

A cake shop has to drop the selling price of a type of cake by $3.6 per unit because the wheat flour cost has decreased 18% or by $0.4 per unit sold. The new flour cost now accounts for 35% of the total selling price. Before the selling price changed, what percent of the total price had flour cost constituted?

Thank you

Hey! Seems like you know a couple of things from the question: 

1. You know that 18% of the original cost $0.4

2. You know that the Cost - 0.4 = 35% of P + 3.6

Between these two facts you have enough to solve the problem! Feel free to reply if you are having trouble getitng to the right answer!

Hi,

I have a hunch that you're the same person that has asked the 3 other quant questions!

I think you're approaching this wrong (if I may).

Rather than spamming the Q&A to get the answer, you need to learn the logic.

Same goes with case types (you can't just memorize every case framework out there...you have to learn how to think about every case prompt individually).

So, I highly recommend you ernestly try to solve each of these problems on their own.Then, post here with your reasoning/thinking and then we can comment on that.

You're not going to ace the case by getting every answer to every question in the world. Rather, you'll learn by figuring out how to think about each one you see! Also, a coach can help you with this :)
