If I can paint a wall in 20 min and my friend can paint a wall in 30 min. How many minutes would it take for us to paint a wall
ra1l [238]

Answer: 12\ \text{min}

Step-by-step explanation:

Given

It takes 20 min and 30 min for  a person and his friend to paint a wall individually  i.e.

In 1 min they cover \frac{1}{20} part and \frac{1}{30} part of wall respectively.

If the work together, 1 minute work is

\Rightarrow \dfrac{1}{20}+\dfrac{1}{30}\\\\\Rightarrow \dfrac{3+2}{60}\\\\\Rightarrow \dfrac{5}{60}

Time required will be reciprocal of it

\Rightarrow \dfrac{60}{5}=12\ \text{min}
