sMr. Yadav pends 90% of his total income and save 10%.
His highest expense is food which is 30% while rent is 20%. Perhaps he can consider lower his food expenses to save more or spend it else where. 15% is spent on Education and clothes each, and spends the same amount on entertainment as he saves that is 10%.
This makes a total spend of 90% of his income and the remaining 10% is saved by him for his own future.
