Question

Consider x as number of primer attribute and y as number of non-prime attribute of relation R(m, n, o, p, q, r, s, t), from given functional dependencies:
$F=(q\to rst,mn\to pqrst,o\to pq,p\to m)$
The value of x × y is _______

• A. 14
• B. 12
• C. 15
• D. 16

Answer 1

The correct option is B 12

determines the entire attribute set of the relation n, o are prime atributes therefore the value of x is 2 and non prime attributes m, p, q, r, s, t therefore the value of y is 6. Therefore, the value of x × y will be 12.
