Details solution
Give data.
Income 2:3
Expenditure 5:9
Income of second year = 45000
Expenditure in first year = 25000
Calculation
Let the income of first year = X
Expenditure in second year = Y
As per question
X/45000 = 2/3
3x= 90000
X = 30000
And
25000/Y = 5/9
5Y= 225000
Y = 45000
Now total saving in two years
(30000-25000) + (45000-45000)
5000 is answer
