If arjun can complete a work in 20 days and aman in 25 days. If they started working togather .but due to some reason ajun stop after 2 days . So in how much time will it take to completee the work? plzz answer mw Fast!

In 20 days Arjun can complete a piece of work.
So, in 1 day Arjun can complete $\frac{1}{20}$ of a work
Similarly, in one day Aman can complete $\frac{1}{25}$ of a work
According to the question Arjun stop after 2 days.
So, In 2 days Arjun completed $\frac{2}{20} \mathrm{i}.\mathrm{e}. \frac{1}{10}$ of a work.
Suppose it takes x days to complete the remaining work.
So, in x days Aman completed $\frac{x}{25}$ of a work.
So we have an equation as;
$$\begin{gathered} \frac{x}{25}+\frac{1}{10} +\frac{2}{25}= 1 \\ \Rightarrow \frac{x}{25} = 1-\frac{1}{10}-\frac{2}{25} \\ \Rightarrow \frac{x}{25} = \frac{50-5-4}{50} \\ \Rightarrow x = \frac{41}{50}\times 25 = \frac{41}{2} = 20\frac{1}{2} \end{gathered}$$
Therefore, total time taken to complete the remaining work is approximately 21 days.
