Assertion:Four digit numbers with different digits is formed with the digits 1,2,3,4,5,6,7 in all possible ways. Then number of numbers which are divisible by 4 is 200. Reason: A number is divisible by 4 if the digit at units place is divisible by 4. (A) Both A and R are true and R is the correct explanation of A (B) Both A and R are true R is not te correct explanation of A (C) A is true but R is false. (D) A is false but R is true.

Assertion : A^-1 exists, Reason: |A|=0 (A) Both A and R are true and R is the correct explanation of A (B) Both A and R are true R is not te correct explanation of A (C) A is true but R is false. (D) A is false but R is true.

Assertion : A^-1 exists, Reason: |A|=0 (A) Both A and R are true and R is the correct explanation of A (B) Both A and R are true R is not te correct explanation of A (C) A is true but R is false. (D) A is false but R is true.

Assertion: Tr(A)=0 Reason: |A|=1 (A) Both A and R are true and R is the correct explanation of A (B) Both A and R are true R is not te correct explanation of A (C) A is true but R is false. (D) both A and R is false.

Assertion (A): z/(4-z^2) lies on y-axis. Reason (R): |z|^2= zbarz (A) Both A and R are true and R is the correct explanation of A (B) Both A and R are true R is not te correct explanation of A (C) A is true but R is false. (D) A is false but R is true.

Statement-1: A number of four different digits is formed with the help of the digits 1,2,3,4,5,6,7 in all possible ways. The number of ways which are exactly divisible by is 200. Statement-2: A number divisible by 4, if units place digit is also divisible by 4.

Assertion: The numbers b_1,b_2,b_3,b_4 are neither in A.P. nor in G.P. Reason: The numbers b_1,b_2,b_3,b_3 are in H.P. (A) Both A and R are true and R is the correct explanation of A (B) Both A and R are true R is not te correct explanation of A (C) A is true but R is false. (D) A is false but R is true.
