Re: Some problems of last year divisionals, I need hel for
$5.$ $AB = 9,$ $AC = 5,$ $BC = 6$ in triangle $ABC$ and the angular bisectors of the three angles are $AD, BF$ and $CE$. Now there is a point in the interior from which the distances of $D, E$ and $F$ are equal. Let this distance be $a$. There’s also another point from which the distances of $A, B$...

Re: from 1 to 100
$1+4=5$ $2+3=5$ $2+4=6$ $1+5=6$ there are many like these. What is the want of the problem. Is $same$ $sum$ means, no matter how, if two pairs get the same summation ? Or, are you talking about the highest number of pairs, which will have the same sum ? If the first assumption is right. only, $1+2=3...

Re: Any Way
A non residential camp for SSC examinees was held in 2011.
I don't know when it will be held again.

Re: Change of temperature by adding water
I wonder, why water of $500^\circ C$ or $200^\circ C$ is called water ?
Is it not vapor ?
And, if it is, should we not add the latent heat ?

Re: Physics
The fact is that, when, our ears, or should I say brain, catches a sound, it remains there for approximately $0.1s$ So, If the distance is too short, that we have to hear the echo in $0.1s$, we can't differentiate it with the real one. But, for echo, the sound wave gets $0.2$ seconds. As, it goes an...
