Answer:

Use prime factors to eliminate possibilities:

Her name = 10x21x4x7x5

She can’t have a U(21), or a G(7), no it must have 2 N(14)

She can’t name an E(5), or a J(10), and can’t have an O(15) because that would mean she would need an E or a J.  So her name has a y(25).

This leaves 2x3.  Since she can’t have a C, she must have an F.  The last factor is a 1, which means A.
