Text Solution

What is known?

Fruits bought by Shyama and Sarala.

What is unknown?

Who bought more fruits.

Reasoning:

Find out total fruits purchased by both Shyama and Sarala then we easily find out who bought more.

Steps: 

Weight of apples bought by Shyama \(=5\,\rm{kg}\ 300\,\rm{g}\)

Weight of mangoes bought by Shyama \(=3\,\rm{kg}\ 250\,\rm{g}\)  

\(\therefore \) Total weight of fruits bought by Shyama

\[\begin{align}&= 5 \,\rm{kg}\ 300 \,\rm{g} + 3 \,\rm{kg}\ 250 \,\rm{g} \\&= 8 \,\rm{kg}\ 550 \,\rm{g}\end{align}\]

Also,

Weight of oranges bought by Sarala \(=4\,\rm{kg}\ 800\,\rm{g}\)

Weight of oranges bought by Sarala \(=4\,\rm{kg}\ 150\,\rm{g}\)

\(\therefore \) Total weight of fruits bought by Sarala

\[\begin{align}&= 4\,\rm{kg}\ 800 \,\rm{g}\ + 4 \,\rm{kg}\ 150 \,\rm{g}\ \\&= 8\,\rm{kg}\ 950\,\rm{kg}\end{align}\]

On comparing the quantity of fruits, we get

\(8\,\rm{kg}\ 950\,\rm{g} > 8 \,\rm{kg}\ 550 \,\rm{kg}\)

Thus, Sarala bought more fruits.
