It is given that Sujita can do 1/4 of the work in one day and Ranju can do 1/8 of the work in 1 day.
If they work together, they would do the work that is equal to:
[tex]\frac{1}{4}+\frac{1}{8}=\frac{2}{8}+\frac{1}{8}=\frac{3}{8}[/tex]So they can do 3/8th of the work in 1 day if they work together.
