Q1: Question: How many gift boxes were sold on Monday ? Statements:
  1. It was 10% more than the boxes sold on the earlier day i.e. Sunday.
  2. Every third visitor to the shop purchased the box and 1500 visitors were there on Sunday

A I alone is sufficient while II alone is not sufficient

B II alone is sufficient while I alone is not sufficient

C Either I or II is sufficient

D Neither I nor II is sufficient

E Both I and II are sufficient

ANS:E - Both I and II are sufficient

Explanation: From II, we can conclude that (1500 * 3) = 500 boxes were sold on Sunday. Thus, from I, we find that number of boxes sold on Monday = 500 + 10% of 500 = 550.
