there are a few ways to go about it..
1 split it in half (equal parts) and weigh both against each other,
which half has lower weight has the defective coin,
repeat until you have only one left
2 split it in 4 or 3 (equal) parts compare 2,
if one has lower the defective coin is in that part,
if both weigh the same the defective part is in
the 2 or 1 part that was not compared

usually explain the first part, and if they say this can be optimised then explain the second method(pause enough so that your answer seems legit 😊)
