Tips on How to Quickly Working Problem-Arithmetic Social
Quick Ways Working Problem-Arithmetic Social - Do you find it difficult when trying to solve the problems concerning the social arithmetic in math? do you know that there is actually a quick way that you can use to work on the problems of social arithmetic? if you did not know it then you is very lucky because in this article will discuss a few tips and tricks on how to fast in the work on the problems relating to the material ang social arithmetic.
Among you there must be a sense of confusion when dealing with issues concerning the social arithmetic. Measures such as whether to take on the solutions? below Basic Mathematical Formulas will give you a few simple steps that can help you in solving problems of social arithmetic. There are two important things you should consider first dalah determines the price of purchase and sale (to solve problems relating to the profit and loss). in the discussion this time we will learn about profit and loss beforehand, while matters concerning loans or savings we'll discuss in another article.
Quick Ways Working Problem-Arithmetic Social
1.Tentukan advance purchase price
You have to figure the amount of the total purchase price (net purchase) terleih first. is a total purchase price / net purchase is the purchase price after deducting the discount (if the goods are subject to a discount) or plus certain expenses. Normally in social arithmetic problems regarding the purchase will be included rebates or discounts.
2.Tentukan sales price
Then you must determine the total sales price (net sales). is the total sales price / net sales is the sales price has been reduced by regular certain costs, such as sales tax or discount (rebate). usually there is also deducted with mass (tare).
3. Set the percentage gain or loss
Once you determine the net purchase price and the net sales price, then you can determine the percentage of profits and losses by using the equations that we have discussed the matter of How calculate the percentage (%) Gain .
So what if the question asks us to determine the sales price or the price purchase? to solve the problems like that there are some similarities that we can use. The first equation is a general equation (basic concept) and the second is a special equation.
The general equation used to specify the percentage of profit and loss are:
While the particular equation we can use in the purchase or sale price menentukah when the percentage of the profit and loss have been known. Persamaanya is:
If you find it difficult to memorize the sixth formula the equation above, choose just one that you think is easier to memorize. general equation can you choose because it is a quick way that you can use to work on the problems of arithmetic. Besides the general equation consists of two formulas only. With the general equation you can perform a variety of questions about the social arithmetic. However, you should understand the concepts of algebra.
so Leih easy to understand the above equation, we just practice to complete examples of problems below:
Example Problem 1:
A motor is sold at Rp. 13,500,000 with a profit of 8%. determine the purchase price!
Solved:
Given: Price Sales = Rp. 13,500,000
Percentage Gain = 8%
Asked: The purchase price = .... ?
Answer:
2 Purchase price = Rp. 337500000-25 purchase price
2 The purchase price The purchase price + 25 = Rp. 337 500 000
27 The purchase price = Rp. 337 500 000
The purchase price = Rp. 337 500 000/27
The purchase price = Rp. 12,500,000
Now we are trying to accomplish by using a special equation.
then:
The purchase price of = Rp. 13,500,000 x 100 / (100 + 8)
The purchase price of = Rp. 13,500,000 x 100/108
The purchase price = Rp. 1,350,000,000 / 108
The purchase price = Rp. 12,500,000
Thus, the purchase price mo tor is Rp. 12,500,000
Example Problem 2:
A bicycle was purchased at a price of Rp. 350,000 and the bike was sold back to a loss of 20%. What is the selling price of the bike?
Solved:
Given: Price Buy = Rp. 350,000
Percentage Losses = 15%
Asked: Selling Price = ....?
Answer:
Rp. 1,750,000 = Rp. 8750000-25 selling price
25 the price = Rp. 8.75 million - Rp. 1.750.000
25 the price = Rp. 7,000,000
selling price = Rp. 7,000,000 / 25
selling price = Rp. 280,000
Now we are trying to accomplish by using a special equation.
Thus:
The purchase price of = (100-20) / 100 x Rp. 350,000
The purchase price of = (80/100) x Rp. 350,000
The purchase price = Rp. 280,000
so, the sales price of the bike is Rp. 280,000.00.
Two examples of questions indicate that special equations and special equation will yield the same answer. In the general equation we must use the concept of algebra while in a special equation we do not need it. In essence, you may choose to use the way that you think is easier. It all depends on the ability of your brain. It seemed enough of a discussion of Tips on How to Quickly Working Social Arithmetic Problem Solved that can be conveyed. Hope can help you to more easily emmahami material on social arithmetic.
