FAQs on Basic problems on Unitary Method Video Lecture - Quantitative Aptitude for SSC CGL

1. What is the unitary method in mathematics?
Ans. The unitary method is a mathematical technique used to solve problems that involve proportionality. It helps in finding the value of one quantity when the value of another quantity is known.
2. How can the unitary method be applied to solve problems?
Ans. To solve problems using the unitary method, you need to establish a proportion between two quantities and then use cross-multiplication to find the unknown value. The proportion can be set up by comparing the ratios of the two given quantities.
3. Can you provide an example of solving a problem using the unitary method?
Ans. Sure! Let's say it takes 4 hours for a machine to produce 60 widgets. How many widgets can the machine produce in 8 hours? First, we set up the proportion: 4 hours = 60 widgets 8 hours = ? Using cross-multiplication, we get: 4 * ? = 8 * 60 ? = (8 * 60) / 4 = 120 Therefore, the machine can produce 120 widgets in 8 hours.
4. Are there any common mistakes to avoid while using the unitary method?
Ans. Yes, one common mistake is forgetting to set up the proportion correctly. Make sure to compare the ratios of the two given quantities accurately. Another mistake is not cross-multiplying correctly, which can lead to incorrect results. Always double-check your calculations.
5. Can the unitary method be used for more complex problems?
Ans. Yes, the unitary method can be applied to solve more complex problems involving multiple quantities. By establishing proportions and using cross-multiplication, you can find the unknown values in these problems as well. Just make sure to set up the correct ratios and perform the calculations accurately.
