Answers
Answer:
. In the matrix A = , write:
(i) The order of the matrix.
(ii) The number of elements.
(iii) Write the elements
Ans. (i) There are 3 horizontal lines (rows) and 4 vertical lines (columns) in the given matrix A.
Therefore, Order of the matrix is 3 x 4.
(ii) The number of elements in the matrix A is 3 x 4 = 12.
(iii) Element in first row and third column = 19
Element in second row and first column = 35
Element in third row and third column =
Element in second row and fourth column = 12
Element in second row and third column =

2. If a matrix has 24 elements, what are possible orders it can order? What, if it has 13 elements?
Ans. Since, a matrix having element is of order
(i) Therefore, there are 8 possible matrices having 24 elements of orders 1 x 24, 2 x 12, 3 x 8, 4 x 6, 24 x 1, 12 x 2, 8 x 3, 6 x 4.
(ii) Prime number 13 = 1 x 13 and 13 x 1
Therefore, there are 2 possible matrices of order 1 x 13 (Row matrix) and 13 x 1 (Column matrix).
3. If a matrix has 18 elements, what are the possible orders it can have? What if has 5 elements?
Ans. Since, a matrix having element is of order
(i) Therefore, there are 6 possible matrices having 18 elements of orders 1 x 18, 2 x 9, 3 x 6, 18 x 1, 9 x 2, 6 x 3.
(ii) Prime number 5 = 1 x 5 and 5 x 1
Therefore, there are 2 possible matrices of order 1 x 5 (Row matrix) and 5 x 1 (Column matrix).

Answer:
Operation Blue Star was the code name of an Indian military action which was carried out between 1 and 8 June,1984, in order to capture the Sikh leader Jarnail Singh Bhindranwale and his followers along with the demolition of the buildings of Harmandir Sahib (Golden Temple) complex in Amritsar, Punjab. The decision to launch the attack rested with Prime Minister Indira Gandhi,[14] who, according to retired general S.K. Sinha, had been considering the operation for more than 18 months prior, authorizing army preparation for it long before any insurgents were in the complex.[15][16] In July 1982, Harchand Singh Longowal, the President of the Sikh political party Akali Dal, had invited Bhindranwale to take up residence in the Golden Temple Complex to evade demolition of Sri Akal Takht Sahib.[17][18] The government said that Bhindranwale later turned the sacred temple complex into an armoury and headquarters.[
