A - Arithmetic Mean is equal to the lightest package. It means that all the packages must weight equal since even if there was 01 package greater than the lightest package, the mean would be slightly higher. But this does not give us the number of packages higher than 420g.
B - Median weight of the packages is 410g. This also alone does not give how many are higher in weight than 420g.
Combining both the statements, all packages weight the same and that weight is 410g. Hence, no package is greater than 420g.
Both statements together are sufficient.
