GDB # 1:

Question # 1:
The salary of an employee is as follows: Basic salary = 20,000 Rs. Allowances =   10,000 Rs.
What is the cost on account of casual, earned and sick leaves per year if normal working days per month is 22? What is the total cost of leaves as percent of gross salary?
 
 
Question # 2:
                                   
Find the Multiplicative Inverse of A and show that A-1A = I, where I is the Identity Matrix. And
  A = 3     2
         4     3
#2
Question 2 Solution

A^-1 = adj(A)/det(A)

Adj(A) = 3 -2
-4 3

det(A) = 9 - 8 = 1

A^-1 = 3/1 -2/1
-4/1 3/1

Now, if you multiply A with A^-1, you will get I, the identity matrix.
