Mr. Balamurali spends 25% of his monthly salary on household expenditure, 20% of the remaining on children’s education, and the remaining is equally invested in three different schemes. If the amount invested in each scheme is Rs.5600, what is the monthly salary of Balamurali?

a) Rs.28000 b) Rs.21000 c) Rs.24000 d) Rs.42000

• let the monthly salary=x
  amount invested on expenditure=x/4;
  remaning amount=3x/4;
  amount invested on children education=20% i.e is 3x/20;
  remaining amount=3x/4 - 3x/20=3x/5;
  remaining amount invested in three different schemes i.e is 1/3(3x/5)
  x/5=5600
  therefore x=28000
  monthly salary is 28000
