Answer

Correct Option is Quantity I < Quantity II

Solution:
Quantity I: For minimum number of invitations,
All of Veer’s friends need to know each other and their friends should be also same i.e.
15 friends should be common to each of his friends.
So, minimum number of invitations = 30
Quantity II: Veer has fifteen friends and each of his friends has 30 friends.
So, apart from veer, each of the fifteen friends have 29 friends each.
As, Veer’s at least two friends know each other
So, maximum number of invitation (When only two friends know each other
= (15 × 29 + 15) –2= 448
