Percent Problem Solving

Now for this question, let us assume the price if the article to be x.

20% of the price then would be (20/100) * x = 0.2x 10% of this would be (10/100) * (0.2x) = 0.02x.

The major challenge in questions based on Percentages are to carefully understand the kind of questions being asked.

You need to know what exactly you must find in a question by reading carefully.

Good thing I did my research and chose this website to outsource all the essays.Answer: 20% of 50 can be calculated by replacing the symbol “%” with “/100” and “of” with the multiplication symbol “*”.For the first part, 20% of 50 = (20/100) * 50 = (1/5) * 50 = 10.For this, the difference of (150-90) is to be divided by 150 and multiplied by 100. Hence, the answer should be (150-90)/150 multiplied with 100, which equals (60/150)*100 = 40. Example 5: Question: If p is q percent of r, then what percent of q is p, in terms of r? Converting the first part of the question into a mathematical equation: “p is” means “p=” “q percent” means “q/100” “of r” means “*r” Hence, the first part gets translated into a mathematical equation: p = (q/100) *r which implies (p/q) = r/100 Now, the second part of the question similarly: “What percent” means “? Lengthy questions can be broken down into simple blocks and converted into mathematical equations.Let’s have a look at a few more examples to understand the above mentioned challenges.Example 4: Question: If the price of a stock increased by 25% on Monday and another 20% on Tuesday, what should the percentage decrease in the price of the stock be on Wednesday so that it is available at a 10% discount to its closing price on the Friday?(Saturday and Sunday are non-trading days for the stock) Answer: We don’t have the closing price of the stock on Friday.One involves testing on percentages itself while the other involves testing on percentage changes.For students attempting tests like the SAT, it is important to read and understand the questions thoroughly.
