In the table below is the listing of players, seeded from highest (#1) to lowest (#32), who are due to play in an Association of Tennis Players (ATP) tournament for women. This tournament has four knockout rounds before the final, i.e., first round, second round, quarterfinals, and semi-finals. In the first round, the highest seeded player plays the lowest seeded player (seed # 32) which is designated match No. 1 of first round; the 2^{nd} seeded player plays the 31^{st} seeded player which is designated match No. 2 of the first round, and so on. Thus, for instance, match No. 16 of first round is to be played between 16^{th} seeded player and the 17^{th} seeded player. In the second round, the winner of match No. 1 of first round plays the winner of match No. 16 of first round and is designated match No. 1 of second round. Similarly, the winner of match No. 2 of first round plays the winner of match No. 15 of first round, and is designated match No. 2 of second round. Thus, for instance, match No. 8 of the second round is to be played between the winner of match No. 8 of first round and the winner of match No. 9 of first round. The same pattern is followed for later rounds as well.

**1.** If there are no upsets (a lower seeded player beating a higher seeded player) in the first round, and only match Nos. 6, 7, and 8 of the second round result in upsets, then who would meet Lindsay Davenport in quarter finals, in case Davenport reaches quarter finals?

1. Justine Henin 2. Nadia Petrova 3. Patty Schnyder 4. Venus Williams

**2**. If Elena Dementieva and Serena Williams lose in the second round, while Justine Henin and Nadia Petrova make it to the semi-finals, then who would play Maria Sharapova in the quarterfinals, in the event Sharapova reaches quarterfinals?

1. Dinara Safina 2. Justine Henin 3. Nadia Petrova 4. Patty Schnyder

**3.** If, in the first round, all even numbered matches (and none of the odd numbered ones) result in upsets, and there are no upsets in the second round, then who could be the lowest seeded player facing Maria Sharapova in semi-finals?

1. Anastasia Myskina 2. Flavia Pennetta 3. Nadia Petrova 4. Svetlana Kuznetsova

**4.** If the top eight seeds make it to the quarterfinals, then who, amongst the players listed below, would definitely not play against Maria Sharapova in the final, in case Sharapova reaches the final?

1. Amelie Mauresmo 2. Elena Dementieva 3. Kim Clijsters 4. Lindsay Davenport

The prospect for a Career in Management is very bright. The Economy is looking up now and there is a demand for Trained people to manage the new companies. The "New Economy" consisting of Internet and Entertainment companies have poached on traditional companies so there is a shortage of Trained Managers. Every year there are reports that there is saturation in the Market, but such rumours are proved wrong every year. MBA remains a good Career choice for Young Graduates with a dream of Successful career.
