m4maths is one of the main reason I cleared TCS aptitude. In TCS few questions will be repeated from previous year aptis and few questions will be repeated from the latest campus drives that happened in various other colleges. So to crack TCS apti its enough to learn some basic concepts from famous apti books and follow all the TCS questions posted in m4maths. This is not only for TCS but for all other companies too. According to me m4maths is best site for clearing apti. Kuddos to the creator of m4maths :)

Yesterday Best Solution

DIPIN

(x-y)^2 + (y-z)^2 + (z-x)^2 >= 0
2 (x^2 + y^2 + z^2 - xy - yz - zx) >= 0
x^ + y^ + z^2 - xy - yz - zx >= 0

so x^2 + y^2 + z^2 - xy - yz - zx < 0
is not possible.

Is this solution helpfull? Yes (3) | No (2)

Hi Team,
Today in the afternoon I got "Parker Pen" as a gift from M4Maths for securing 96 marks in a week,Although i scored 96 marks in a week i was in suspicion whether i will get prize from M4Maths Team or not, Because most of the online website will be fraud only they will write greedy offers on their website but in the last they will not send prize or gift whatever they will commit to the users.But it did not happen with me as i got prize from M4Maths Team i am very very thankful to M4Maths Team.
