ICSE − Q & A

If both roots of ax^2+bx+a-c =0 are imaginary and a b and c are real numbers and c>-1 then establish relation between a b and c

Guys plz check whether this question is wrong or not :-
In H atom the energy of electron in the nth orbit is given as En = -13.6/n².
Show that E(n+1) - En = -13.6/n²  eV*2 for large value of n.

#By large value of n ---> you can consider n+1 ~ n

1 mole mixture of N2,NO2,N2O4 has a mean molar mass 55.4 on heating to temprature at  which all hte N2O4 dissociate  into NO2 according to raction
(N2O4 double headed arrow 2NO2) and average molar mass becomes 39.6.what is the mole ratio of N2,NO2,N2O4 ????? [ANSWER:0.5:0.1:0.4]

is there any jee group or hsc group on respaper

मैं पता करना चाहूँगा की आप लोगो ने कोन कोन सी क्लास्सेस एव कॉलेज में एडमिशन लिया है ??(यह भी बताए की वह इंटीग्रेटेड है या नहीं)

Guys check the official site out. They were so fed up by what happened today that they themselves declared that they will notify 48 hours before the results are declared.

Now, this is really getting frustrating. NO MORE RESULT UPDATES ON THIS Q/A PAGE UNTIL ICSE OFFICAILLY DECLARES IT ON CISCE.ORG. NOW, I SUPPOSE THAT IS CLEAR. NO HOAXES FROM DUMB NEWS CHANNELS OR WEBSITES.

P.S.: mind the caps

I am seriously tired of these fake news getting around regarding the board results. Isn't it becoming really interesting that the exam dates were changed once and now there is much fuss regarding the result announcement dates in this year's icse exam?

Hey guys.... NO  RESULT TODAY..............THIS IS FINAL............I contacted the Council on the number (011) 29564833 and the person clearly stated that the result is not coming out today. That was all fake news spread by unscrupulous trp hunters(news channels). He emphasised that the date will be updated on the Council website(www.cisce.org) beforehand, so there is no reason for wild speculation. I am sorry for the previous post about the result, because the news seemed credible, and it was rash. My sincere request to all those who are reading this message is to calm down and not to give in to any of these fake news vendors. And please, for the sake of humanity, kindly do not contact the Council, because those guys will be getting so many calls already, and you know how irrititaing it is to reiterate the same thing again and again to each and every person( @sdfg will know this better than anyone else). Kindly believe what I, @haxer, @sdfg, and @makaveli have confirmed. And please STOP posting speculated dates. 6th, 10th, 15th....all have been eliminated, which proves that no one out there knows the date, except the Council(and presently, I think even they don't know it..;p). So please be calm and collected.

Cheers!! 
And All the Best for the result whenever it comes!!!!!!

Guys exactly when is the result??
