The respective ratio between the monthly salaries of Rene and Som is 5 : 3. Out of her monthly salary Rene gives 1/6th as rent, 1/5th to her month, 30% as her education loan and keeps 25% aside for miscellaneous expenditure. Remaining INR 5000/- she keeps as savings. What is Som's monthly salary
Let the monthly salaries of Rene and Som be 5x and 3x respectively.
Accordingly to question,
5x[1-1/6-1/5-30/100-25/100]=5000
5x[1-1/6-1/5-3/10-1/4]=5000
5x[60-10-12-18-15/60]=5000
x[5/60]=1000
x=INR 12000/-
∴ Som's monthly salary = 3×12000 = INR 36000/-
