The following are the steps in finding the matrix B, if B + ({:(2, 3), (4, 5):}) = ({:(5, 4), (3, 2):}) . Arrange them in sequential order. (A) therefore ({:(p, q), (r, s):}) + ({:(2, 3), (4, 5):}) = ({:(5, 4), (3, 2):}) (B) Let B = ({:(p, q), (r, s):}) (C) ({:(p+2, q+3), (r+4, s+5):}) = ({:(5, 4), (3, 2):}) (D) P + 2 = 5, q + 3 = 4, r+ 4 = 3, s + 5 = 2 rArr p = 3, q = 1, r = -1, s = -3 (E) therefore B = ({:(3, 1), (-1, -3):})

Points A(4, 5, 1), B (0, - 1, - 1), C (3 , 9, 4) and D( -4, 4, 4) are

If A = { 3 , 5 , 7 , 9 , 4 }, B = { 1, 3, 5 } , C = { 2, 4, 6 ,7 } ; then A - { B ∩ C } =

Arrange the words given below in a meaningful sequence. 1. Shoulder 2. Wrist 3. Elbow 4. Palm 5. Finger (A) 5 4 2 3 1 (B) 3 4 5 2 1 (C) 3 1 4 2 5 (D) 2 4 5 3 1

If A = {1, 2, 3}, B = {3, 4, 5}, then (A nn B) xx A is

If A = {1, 2, 3, 4}, B = {3, 4, 5} and C = {1, 4, 5} then the value of A - (B - C) is

If A = {1, 2, 3, 4}, B = {3, 4, 5} and C = {1, 4, 5} then the value of A – (B nn C) is

If A = [ [ 1 , 2 ] , [ 3 , 4 ] ] & B = [ [ 4 , 2 ] , [ 1 , 1 ] ] , then ( A + B )' is equal to : ( a ) [ [ 5 ,4 ] , [ 4 , 5 ] ] ( b ) [ [ 5 , 4 ] , [ 5 , 5 ] ] ( c ) [ [ 5 , 4 ] , [ 3 , 5 ] ] ( d ) [ [ 5 , 5 ] , [ 4 , 4 ] ]

If A = {1, 2, 3, 4}, B = {3, 4, 5} and C = {1, 4, 5}, then the value of A nn (B uu C) is

If A = { 1,2,3,4 }, B = { 2, 4, 5,6 } , U = { 1,2,3,4,5,6,7} then A' ∩ B'
