Answer : Option A
Explanation :
Let the First-year income = 2x
And, Second-year income = 3x
But ATQ, the second-year income = 45000
So, x = 45000/3 = 15000
Then, first-year income = 2*15000=30000
Similarly,
Let the first-year expenditure = 5y
But ATQ, the first-year expenditure =25000
So, y = 25000/5 = 5000
Second-year expenditure = 9y= 9* 5000 = 45000
Apply formula:
Income = expenditure + savings
Or, savings = income - expenditure
Or, first-year savings = 30000- 25000 = 5000
Similarly,
Second-year savings = 45000- 45000 = 0
Now, total saving in two years = first-year savings + second-year savings
Or, Total saving = 5000+0 = 5000.
