Equivalent 1000Ω Resistor Uncertainty

[the_d]

my question is that i have two resistors that are combined to form an equivalent resistance of 1000 ohms. Now there are two common resistors rated at 500 plus/minus 50 ohms and two others rated at 2000 ohms plus/minus 5%. I need to know what combo (series or parallel) would provide the smaller uincertainty in the equivalent 1000 ohm resistance?

This is probably a homework question as manufacturers usually don't spec tolerance in this way. so...

what have you tried so far? do you have an opinion?

Thread moved to homework forum.

the_d, just do the math to figure it out. Do the combinations of resistors that are at the extreme +/- of their tolerances. What answer do you get?
