means "similarity" or "similar relation ship". In questions
on number or letter analogies, a pair, that has a certain relationship between
them, is given. This number/letter pair is followed by a third number/letter.
The student is expected to identify the relationship between the pair given and
find out a FOURTH number such that the relationship between the third and the
fourth is similar to the relationship that exists between the first and the
second. (In some cases, it may not be the fourth one that has to be found out.
The fourth one will be given and the student has to find out one of the other
three, whichever is not given).
