About
Simple and Easy Learning
Tutorials Point originated from the idea that there exists a class of readers who respond better to online content and prefer to learn new skills at their own pace from the comforts of their drawing rooms.
The journey commenced with a single tutorial on HTML in 2006 and elated by the response it generated, we worked our way to adding fresh tutorials to our repository which now proudly flaunts a wealth of tutorials and allied articles on topics ranging from programming languages to web designing to academics and much more.
40 million readers read 100 million pages every month
Our Text Library Content and resources are freely available and we prefer to keep it that way to encourage our readers acquire as many skills as they would like to. We don't force our readers to sign up with us or submit their details either to use our Free Text Tutorials Library. No preconditions and no impediments, Just Simply Easy Learning!
We have established a Digital Content Marketplace to sell Video Courses and eBooks at a very nominal cost. You will have to register with us to avail these premium services.

Solution:$(i)$. Given ratio$=10:3:12$Total part$=10+3+12=25$Part of Carbon$=\frac{3}{25}$Percentage of Carbon part in chalk$=\frac{3}{25}\times100=12$ % $(ii)$. Quantity of Carbon in chalk stick$=3\ g$Let the weight of chalk be $x\ g$.Then, $12$ % of $x=3$$\Rightarrow\ \frac{12}{100}\times x=3$$\Rightarrow x=\frac{3\times100}{12}=25\ g$Hence the weight of the chalk stick is $25\ g$.Read More
