Given, Shyama bought 5kg 300g =5,300 g apples and 3kg 250g =3,250 g mangoes.
Total fruit bought by Shyam is 5,300+3,250=8,550g.......(1).
Also given, Sarala bought 4kg 800g =4,800g oranges and 4kg 150g =4,150g bananas.
So total fruit bought by Sarala is 4,800+4,150=8,950 g.......(2).
Since 8,950>8,550 so Sarala bought more fruit than Shyam.
