Question 773489
<pre>
15% credited to FD account.
What remains is: 100 - 15 = 85%
30% of this is spent in groceries.
%age spent in groceries = 85%*30% = 25.5%
So total amount spent = 15% + 25.5% = 40.5% of his salary.
What is remaining finally: 100 - 40.5 = 59.5%

59.5% of his salary is 2389.
So, if his salary is x, 
{{{x * 59.5/100 = 2389}}}
So {{{x = 2389*100/59.5 = highlight(4015.13)}}}
Salary = 4015.13
Hope you got it :)
