1) Find the area of the circle inscribed in a square having diameter as 16sqrt(2) 2) Given mean of three numbers 2x,7x, and x^2 is 12. find the range of the numbers.here i got x=3 and -12 how can we find the range? 3) Which of the following can not be necessarily true?
c) a^2+b^2=c^2d) atleast two are acute anglesfor this C and B are not necessarily true. am i correct? 4) Given (x-3)/x-1)<0 where x>1 find x? 5) If three sides of a quadrilateral are equal and are of the x cm, then find the perimeter of quadrilateral.here the fourth angle must be equal to x. So it is 4x.is it correct? 6) In a group 7 out of 15 students admitted in a university and one of them absent everyday. If 315 students were admitted last month, how many students were not absent at all? 7) If a person 'A' did 1/5th of the work and another 'B' did 1/6th of the remaining work. what is the work still left?
8) A computer system digit code has 5 digits in that 'x' repeats once, y repeats twice and z repeats twice system accepts this code xyzyz and yyxzzcolA:the number possible for the system codecolB:xxx(some value)
