Given:

Shyama bought 5 kg 300 g apples and 3 kg 250 g mangoes. Sarala bought 4 kg 800 g oranges and 4 kg 150 g bananas.

To do:

We have to find who bought more.

Solution:

We know that,

$1000\ g=1\ kg$

According to the question,

Weight of apples bought by Shyama $=5\ kg\ 300\ g$ 

$=5\ kg+0.3\ kg=5.3\ kg$       [Since, $300\ g=300\times(\frac{1}{1000})\ kg=0.3\ kg$]

Weight of mangoes bought by Shyama$=3\ kg\ 250\ g$ 

$=3\ kg+0.25\ kg=3.25\ kg$     [Since, $250 g=250\times(\frac{1}{1000})\ kg=0.25\ kg$]

Total weight of fruits bought by Shyama$=5.3\ kg+3.25\ kg=8.55\ kg$

Weight of oranges bought by Sarala$=4\ kg\ 800\ g$

$= 4\ kg+0.8\ kg=4.8\ kg$     [Since, $800 g=800\times(\frac{1}{1000})\ kg=0.8\ kg$]

Weight of bananas bought by Sarala$=4\ kg\ 150\ g$

$=4\ kg+0.15\ kg=4.15\ kg$     [Since, $150\ g=250\times(\frac{1}{1000})\ kg=1.5\ kg$]

Total weight of fruits bought by Sarala $=4.8\ kg+4.15\ kg=8.95\ kg$

On comparing the quantity of fruits, we get

$8.95\ kg$ > $8.55\ kg$

Thus, Sarala bought more fruits.
