Ravana 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 ` 2500. What is Ravana’s salary

• Rs. 10000
  
  If Ravana's total salary= x Rs., then
  Expenditure on house rent=x*30/100=0.3x
  30% on the remaining(=0.7x) on children's education=0.7x*30/100=0.21x
  Expenditure on clothes=x*24/100=0.24x
  So Remaining salary=x - (0.3x + 0,21x + 0.24x)=2500
  x - 0.75x= 2500
  x=2500/0.25 =10000

• 30% on house rent
  30% on education
  24% on clothes
  
  left with Rs.2500/-
  
  total salary =100%(say)
  expenditure %= 30+30+24=84%
  
  amount left %=(100-84) % ie 16%
  
  now, using formula of percentage calculation: (amount left/total amount)*100=amount left %
  
  assume total amount=x
  
  therefore, we have: (2500/x)*100=16
  then x=31,250 rupees
