Question: How many speeches were delivered in the two days programme ?
Statements:
18 speakers were invited to give at least one speech (maximum of two speech), out of which one-sixth of the speakers could not come.
One-third of the speakers gave two speeches each.
I alone is sufficient while II alone is not sufficient
II alone is sufficient while I alone is not sufficient
Either I or II is sufficient
Both I and II are sufficient
Explanation:
From I, we find that number of speakers who attended programme =18-(1/6) of 18 = 15.From II, we find that one-third of 15 i.e. 5 speakers gave 2 speeches each, while each of the remaining 10 speakers delivered only one speech.So, total number of speeches delivered = (5 x 2 + 10 x 1) = 20.
