Each time you weigh 4 tablets.
the set which weighs more has the poisonous tablet.
hence the set which weighs less has tablets that arent poisonous.

so we have to compare the tablet from the set that has a poisonous tablet with any tablet from the other set.
the tablet that weighs more is the poisonous tablet.
