Q7 A(ii)  http://www.respaper.com/anurag2001/6241-pdf.html

another doubt is while computing matrix sums say A  is some matrix 
and we get A^2+5I= null matrix, in the conclusion should we write 
A^2+5I=0(just zero) or as 0 0 (a null matrix)
                                          0 0

Guys I think that the paper this year would be comparatively tougher than the other years there are two reasons - 1) the science papers and other papers were too easy and 2) they've given a 10 day holiday I mean which board does that??? They would have thought since maths is the toughest paper this year lets give it a 10 day holiday in revised time table how many of you agree w me?? Or you think the paper would be as easy as other years ??( lemme know why?)

In banking, 
1)For eg., should 565 be rounded off to 560 or 570?
2) When we get the interest ( final and.) should we remove the decimal part??

Guys instead of improving my performance is  impairing guys please share some tips to overcome this.
