Question

Amutha can weave a saree in 18 days. Anjali is twice as good a weaver as Amutha.
If both of them weave together, in how many days can they complete weaving the saree?
​

Answer 1

They can complete together weaving the saree in 6 days.

Step-by-step explanation:

Amutha takes time to weave a saree = 18 days

∵ Anjali is twice as good weaver as Amutha, so she takes half time.

∴ Anjali takes time to weave a saree = $\frac{18}{2}$ = 9 days

In one day Amutha can weave saree = $\frac{1}{18}$

In one day Anjali can weave saree = $\frac{1}{9}$

Together they can weave saree per day  = $\frac{1}{18}+\frac{1}{9}$

                                                                     = $\frac{1+2}{18} = \frac{3}{18}$

                                                                      = $\frac{1}{6}$

They can complete together weaving the saree in 6 days.
