FAQs on RS Aggarwal Solutions Class 7 Chapter-9 Unitary Method (Ex 9B) Exercise 9.2
1. What is the unitary method as discussed by RS Aggarwal class 7 Maths chapter 9, and how does it work?
Yes, it works for businesses to calculate their long term or short term profit or losses. The unitary method is a method for determining the value of a single unit and then calculating the value of the requisite number of units based on that value. It makes it simple to solve a variety of problems. It is based on the concepts of proportion and ratio.
2. What are two types of unitary methods?
Direct Variation - When one quantity increases or decreases, it causes the next quantity to rise or decrease as well.
For example, as the number of things increases, the price rises. The quantity of work done by a group of guys is significantly greater than the amount done by a single man.
Inverse Variation - Inverse variation is the inverse of direct variation. The amount of two sets is inversely proportional, meaning that increasing one causes the other to decrease.
3. How can I prepare for my Class 7 Maths exams?
It is critical to create a study strategy. Mark all of the significant dates on a calendar.
Make a list of all the important dates from the exam schedule.
Set aside Sunday each week to create a weekly plan.
Also, make a note of any dates when you have other obligations (like extracurricular activity or family outing)
The planning process appears to take a long time, yet it only takes 15 minutes every week. It's a good use of your time because you'll be productive for the rest of the week. More importantly, stick to your study schedule at all times. It helps to develop discipline over time.
4. How to study for class 7 chapter 9 of RS Aggarwal?
Many students believe that they may start studying a few weeks before the examinations and get the grades they want. When the time comes to study, they despise it and can't seem to find any interest in it. Do not wait until the last minute to prepare. To improve at anything, you must recognise that the only thing you need to do is practise. Hard work is necessary in practicing. The more you practise, the better you'll get.
5. Why is the Unitary method used according to class 7 chapter 9?
The unitary method, in simple words, is used to calculate the value of a single unit from a specified multiple. Furthermore, once the value of a single unit has been determined, the value of the required units can be calculated by multiplying the single value unit. This approach is mostly used to calculate ratios and proportions. Always write the things to be computed on the right-hand side and the things known on the left-hand side to simplify things.
