Answer 2

Answer:

$\frac{3}{5}$  

Step-by-step explanation:

Given :S and T can finish a work in 50 days. they worked for 20 days together and then left.

To Find :how much of the work is left.

Solution:

S and T can finish a part of work in 50 days = 1

S and T can finish a part of work in 1 day =$\frac{1}{50}$

S and T can finish a part of work in 20 days =$\frac{1}{50} \times 20$

                                                                        =$\frac{2}{5}$

Amount of work left after 20 days = $1-\frac{2}{5}$

                                                       = $\frac{3}{5}$  

Hence Amount of work left after 20 days is  $\frac{3}{5}$
