RS Aggarwal Solutions Class 7 Chapter-9 Unitary Method

The unitary method comprises identifying the value of a single unit before moving on to calculating the value of a group of units. What options do you have for units and values?


When employing the unitary strategy to solve an issue, it's vital to understand the units and values.


Always write the elements that need to be computed on the right side of the page and the things you already know on the left. In the scenario above, the number of mangoes is known, but the value of the mangoes is unknown.


Assume you're going to the market to purchase 10 apples. The vendor informs you that 5 apples are for 150. In this situation, the bananas are the units, and the cost of the fruit is the value.

FAQs on RS Aggarwal Solutions Class 7 Chapter-9 Unitary Method (Ex 9C) Exercise 9.3

1. What is the unitary technique as discussed in chapter 9 of class 7 RS Aggarwal, and how effective is it?

The unitary technique can be used by enterprises to calculate long-term or short-term profits and losses. The unitary method is a method for identifying the value of a single unit and then using that value to calculate the value of the required number of units. It simplifies the solution to a wide range of problems. It is based on proportion and ratio notions.

2. What are the two different kinds of unitary methods as discussed in chapter 9 of class 7 RS Aggarwal?

Direct variation occurs when one quantity rises or falls, causing the following quantity to rise or fall in response.


For instance, when the number of items increases, so does the price. The amount of work completed by a group of guys is substantially more than that of a single man.


Inverse Variation - The inverse of direct variation is inverse variation. The size of two sets is inversely proportional, which means that increasing the size of one causes the size of the other to decrease.

3. According to chapter 9 of class 7 RS Aggarwal, what role does the Unitary Method have in our daily lives?

The unitary technique is quite effective in resolving a wide range of problems that we face on a daily basis. Some of the unitary method's real-world applications are as follows:


For eg Calculate the speed of an object for a certain distance if the speed and distance are given in different integers.


To calculate the number of employees required to complete a specific amount of work.

4. According to chapter 9 of class 7 RS Aggarwal, what are the advantages of using the Unitary method?

In simple terms, the unitary approach is used to find the value of a single unit from a given multiple. Furthermore, after the value of a single unit has been identified, the value of the required units can be estimated by multiplying the single value unit by the number of required units. To determine ratios and proportions, this method is commonly employed. To make things easier, always write the items to be computed on the right side and the things known on the left.

5. What is the best way for me to prepare for the chapter 9 Unitary Method of RS Aggarwal Class 7 Maths?

We may compute the value of one unit from the value of many units, as well as the value of many units from the value of one unit, using the unitary technique. For the vast majority of mathematical calculations, we employ this method. This method can be applied to problems in ratio and proportion, geometry, algebra, and other areas.


Using the unitary strategy, we can locate the missing value. How much would three packets of cheese cost if one packet of cheese costs $10? We can easily figure out that three-cheese packets will cost $ 25.
