Hint: Swati working $4$ hours in a day we have to calculate the number of sarees she stitched in $18$ days. After that we will get the estimate of $1$ saree stitched by Swati. Then calculate the time taken in weaving $1$ saree. After that we have to calculate the time detained for weaving $10$ saree.

Complete step-by-step solution:
On working $4$ hours on a daily basis, Swati is able to stich $5$ saree in $18$ days
The girl is working $4$ hours on a daily basis, here we assume that, the one day is equal to $4$ hours
She can weave $5$ sarees in $18 \times 4\,hour = 72\,hours$
The time consumed in weaving $1$ saree in $\dfrac{{72}}{5}\,hours$ = $14.4\,hours$.
The consumption of time in weaving $1\;saree = 14.4\,\;hours{\text{ }}per{\text{ }}saree$
The time consumed for $10$ sarees $= 14.4\,hrs/saree \times 10\;saree{\text{ }} = 144\,hours$
In case that girl started investing about $6$ hours a day, let us assume that one day is equal to $6$ hours
The total detained for the stitching of $10$ sarees $= 144 \times \dfrac{1}{6} = {\text{ }}24{\text{ }}days$.

Note: The type of solution above comes under the category of a method called unitary method. Unitary method is a method in which we first try to find out the value of a single unit and then find the necessary value which is asked by multiplying the single unit value.
