Welcome back!
@soumitrabengeri said:I figured this out from the options..either the answer is c or dI cant find a way to solve the problem, but the answer comes out to be the same with options 1 and 21039C1*961C3 + 1039C3+961C1..considering 1039 -ve elements1039C3*961C1 + 1039C1*961C3..considering 961 -ve elements
yes you are close to the ans..its c by the way...lekin mujhe smajh nai a rah k ise approach kaise kara jaye...it was pretty tough..
@albiesriram said:some progressions...edit :- typo error sorry.. sorry!!find 1^2+2^2 +3^2+5^2+8^2+...upto 100 terms..options..1) 13581 2) 14796 3) 16234 4) 10100 4) none of these
anybody??
@soham2208 said:@nick_baba But, how could we solve this fourth degree equation ? I used wolfram method
see buddy as i said..set theory is not my cup of tea..so can't comment on this much...
n there's no specific way to solve a fourth degree equation..u can reduce it to a quadratic if u want..or if u r comfortable with complex algebra..go ahead with it
@albiesriram said:anybody??
it cud be done using method
Sum of square of febonnaci series= f(n)*f(n+1)
need to calculate f(100) and f(101) for this.
@albiesriram yea,wested almost 3 to 4 minutes and end up wrong ans..i guessed the last digit should be 2.out of 2 option,luck won't be in my favour :(
In a Rectangle, the perpendicular bisector of AC divide the longer side AB in ratio of 2:1. then angle between AC and BD
30,45,60,90
@albiesriram said:@maddy2807 isnt it n*n+1 ??
no it shud be F(100)*F(101)-1
but i dont knw how to calculate F(100)
consider a right angle triangle of perimeter 48.inside triangle,there is circle,inside circle there is square,find the area of the square given that circle touches the hypotenuse divide it in ratio 2:3?
