Hint: Take the total weight of fruits bought by Shyama and Sarala. Then convert it into one form $kg$ or $g$. Compare it you will get the answer.

Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies.

The basic SI unit of mass is the kilogram ($kg$). In physics, mass is not the same as weight, even though mass is often determined by measuring the object's weight using a spring scale, rather than balance scale comparing it directly with known masses.

An object on the Moon would weigh less than it does on Earth because of the lower gravity, but it would still have the same mass. This is because weight is a force, while mass is the property that (along with gravity) determines the strength of this force.

One may distinguish conceptually between at least seven different aspects of mass or seven physical notions that involve the concept of mass. Every experiment to date has shown these seven values to be proportional, and in some cases equal, and this proportionality gives rise to the abstract concept of mass.

The force known as "weight" is proportional to mass and acceleration in all situations where the mass is accelerated away from free fall.

So fruits bought by Shyama are apples and mangoes.

Now the weight of apples is $5kg300g$.

The weight of mangoes is $3kg250g$.

So we know the conversion, $1kg=1000g$.

So converting we get,

Weight of apples$=(5\times 1000+300)g=5300g$

Weight of mangoes$=(3\times 1000+250)g=3250g$

So total weight of fruits bought by Shyama$=$weight of apple$+$weight of mangoes $=5300+3250=8550g=(8\times 1000+550)g=8kg550g$

So the total weight of fruits bought by Shyama is $8550g$ or $8kg550g$. ……………………..(1)

Now for Sarala, the weight of oranges she bought is $4kg800g$.

Weight of bananas is $4kg150g$.

So we know the conversion, $1kg=1000g$

So converting we get,

Weight of apples $=(4\times 1000+800)g=4800g$

Weight of mangoes $=(4\times 1000+150)g=4150g$

So total weight of fruits bought by Sarala$=$weight of oranges$+$weight of bananas$=4800+4150=8950g=(8\times 1000+950)g=8kg950g$

So the total weight of fruits bought by Sarala is $8950g$ or $8kg950g$. ……………………….(2)

So from (1) and (2), we can see $8950g>8550g$.

So Sarala has bought more fruits than Shyama.

Note: Read the question carefully. Do not jumble yourself while conversion. You should know the conversion that is $1kg=1000g$. While comparing, convert it in one form and then compare otherwise confusion occurs.
