That is becoz people (in India at least and most parts of the world), tend to take up either Engineering or Medical and these requires 3 different subjects. Eng requires PCM while med requires PCB. There are only a few who take up both these fields so they happen to be contradictory in that case...

What are PCM and PCB? Are those "PC" referring to the same thing?

"P" here means Physics, "C" means Chemistry, "B" means Biology and "M" means maths. I hope you ca figure it out now.

Wow, I have been a member for 2 years here, yet I never knew that members can't private message each other.

Yeah, it is a feature which is available only to moderators and administrators, which I dislike very much about this forum sad

Are you talking about solving a system of linear equations or just a single linear equation. If latter is the case then you can go here to learn more:http://www.mathsisfun.com/algebra/index.html. If former case, then you can use cramer's rule to solve it. For more info, visit here:https://en.wikipedia.org/wiki/Cramer%27s_rule

You can use Desmos Graphing Calculator to learn about it, the best graphing calculator as far as I know. It contains a lots and lots of features, to help you learn graphs.

You are given 8 balls. One of the balls is heavier than the rest which are all the same weight. It is impossible to determine the heavier ball by the shape, size or lifting it up. You are given a 2-plated beam balance. Using the balance twice, how can you determine which ball is heavier.

Please can we let this thread fade away so it doesn't give anything away.  Thanks.

A better option is to close this topic.

Administrators and moderators have access to additional information about each member

Do they include e-mail address also?

Where did you get 0.571143115080177 from?

See the graph which Ganesh posted. You will see that it converges down to X-axis and almost touches it at that value.

And is that xyz = 1 rather than abc = 1  ?

Bob

Yeah it is.

I solved it but it took 2 whole pages to solve it. Phew! I finally got the numerator and denominator as equal and hence it is equal to 1.
