Answer:
The initial expenditure of the company on salary is Rs. 72.000
Explanation:
First we need to express the employees ratio in letter
3A=B
2C=D
A and C being the amount of employees
B the salary before, D the salary after
They say the salary after is the slary before minus Rs. 12.000
we can express this as D=B-12.000
We know to that the salary of each employee increased 4 to 5
Then C=(5/4)A or A=(4/5)C
We can have the following equation
2((5/4)A)=B-12.000
A=(2/5)(B-12.000)
we use this in the first expression
3(2/5)(B-12.000)=B
1,2B-14400=B
0,2B=14400
B=72.000
