Answer :
Given : Varna bought 4 packets of peanuts , each weighing 250.50 gm , So
Total weight of peanuts bought by Varna = 250.50 4 = 1002 gm
And , Shruthi bought 3 packets of peanuts, each weighing 330.85 gm , So
Total weight of peanuts bought by Shurthi = 330.85 3 = 992.55 gm
Here we can see that Varna bought more peanuts ( in weight ) .
Therefore ,
Varna bought more peanut by weight = 1002 - 992.55 = 9.45 gm ( Ans )
