Question

Answer 1

A to B many to one relationship - which returns 100 entities.

A to C many to one relationship - which returns 10 entities.

B to C one to one relationship - which returns 10 entities.

So maximum number of triples of entities in relationship set R is 10 * 100 = 1000

Comments

can you please explain the question properly.Here A,B,C all are the entities.So how can they consist of entities.I got the question from a test series.

They want to say A is a particular type which have 100 entities.

similarly B is another type and C is another type which have 1000 and 10 entities respectively .
