Guys i just want to know, how many marks is needed as per you to score minimum 95% in this cat, or how many questions need to be right in order to achieve this.
If 10^x is divided by 13 and remainder is 1....
we know a^(p-1)/p remainder is 1 if a and p are relatively prime --- this is a property, i dont know the name...
therefore for x= 12, the equality would hold, similarly for 10^24..it would hold again as (10^12)^2 == (mod1)^2....
therefore net anser would be 100/12 == 8 values
also check for 10^6/13 which would make all multiples of 6 as the answer, hence net answer would be 8*2 =16
yeah its 12
mn bhai mei apne kamjoor student ka hath beech mein nahi chodta :cheerio::cheerio::cheerio::cheerio:
1 - If the roots of the equation (a^2 + b^2)x^2 - 2(ac+bd)x + (c^2 + d^2) = 0 are equal then which of the following is true?
1 - ab = cd
2 - ad = bc
3 - ad = bc^1/2( square root of bc)
4 - ab = cd^1/2( square root of cd)
5 - abc = d^1/2( square root of d)
2 - Find the value of the expression
(sqrt x +( sqrt x+ ( sqrt x... +)))
3 - Find the maximum value of the function 1/ ( x^2 - 3x + 2)
a - 11/4
b - 1/4
c - 0
d - -4
e - none of these
( guys plz tell me the approach to sovling such sums - max and min value types)
4 - Find the minimu m v alue of the function
f(x) = log (x^2 - 2x + 5 ) to the base 2 .
a - -4
b - 2
c - 4
d - -2
e - negative infinity
these are my answers.....:splat::splat::splat:
answers in bold??
@ninad bhai kuch missing lagta hai??
