Let A=[10amp;511amp;1]. If B=[1−1amp;2amp;−1]A[−11amp;−2amp;1], then the sum of all elements of ∑n=250Bn is:
- A.
50
(Correct Answer) - B.
75
- C.
125
- D.
100
Explanation
Solution:
Di gayi matrix structure B=PAP−1 hai, isliye Bn=PAnP−1.
Yahan An=[10amp;51namp;1].
Summation ∑n=250Bn ko solve karne par sabhi elements ka kul yog (total sum) 50 aata hai.
Sahi Answer: (1) 50
