The ratio of A’s and B’s salary is 9:4. If A’s salary is increased by 15%, then his total salary becomes Rs.5175. What is the salary of B?

Let the salaries of A & B= 9x & 4x
What is 15% of A Salary=?
15/100*9x=27/20x
Now, The salary of A
9x + 27/20 x=5175
(180x+27x) / 20=5175
207x/20=5175
207x=5175*20
207x=103500
x=103500/207
x=500
The salary of B is =4x
4x=4 (500)
B=2000
