Answer» $\begin{matrix} Column I & Column II a. If A is an indempotent matrix and I is an identity matrix of the same order, then the value of n, such that (A + I)^{n} = I + 127 A is & p . 9 b. If (I - A)^{- 1} = I + A + A^{2} + . . . . + A^{7}, then A^{n} = 0 where n is & q. 10 c. If A is matrix such that a_{i j} = (i + j) (i - j), then A is singular if order of marix is & r . 7 d. If a non-singular matrix A is symmetric, show that A^{- 1} is also symmetric, then order of A can be & s . 8 \end{matrix}$ Which of the following options is/are correct?
