Step-by-step explanation:

Ruma - - - - - - - - - - - - Work?

               Statement

= Ruma can complete a piece of work in 3 days

= Seema alone can complete in 6days

                     Sloution

= Ruma can complete a piece of work in 3 days

= Work done by Ruma in one days  = $\frac{1}{3}$

=  Seema alone can complete in 6day

= Work done by Seema in one day = $\frac{1}{6}$

      (Ruma one day work) + (Seema one day work)

   $\frac{1}{3}$+$\frac{1}{6}$  = $\frac{2+1}{6}$ = $\frac{3}{6}$  = $\frac{1}{2}$

WORK DONE BY RUMA AND SEEMA IS = $\frac{1}{2}$
