Ram spends 30% of his salary on house rent, 30% of the rest he spends on his children's education and 24% of the total salary he spends on clothes. After his expenditure, he is left with Rs. 2500. What is Ram's salary?

Explanation:-

Let Ram's salary be x.
He spends on rent = 30% of x = 30x/100.
He spends on education = 30% from rest of the salary= (30*70x)/(100*100) = 21x/100.
He Spends on clothes = 24% of total salary = 24x/100.
Saving = 2500.
Salary of ram = x.
(30x/100) + (21x/100) + (24x/100) + 2500 = x.
(75x/100) = x-2500.
75x = 100x-250000.
Or, 100x-77x = 250000.
Or, x = 250000/25.
Or, x = 10000.
Ram's salary = Rs. 10000.
