Given monthly savings of Amit and Bharat are in the ration 37:18. Let the savings of Amit and Bharat be 37k and 18k, where 'k' is a constant.
=> Total monthly savings of Amit and Bharat = 55k.
Given Total annual savings of Amit and Bharat = 1,32,000.
=> Total monthly savings = 11,000.
=> 55k = 11000
=> k = 200.
Hence monthly savings of Amit and Bharat are 7400 and 3600 respectively.
From the given data,
Let the monthly incomes of Amit and Bharat be 5x and 4x respectively, where 'x' is a constant.
Similalrly, let the monthly expenditures of Amit and Bharat be 19y and 21y respectively, where 'y' is a
constant.
Savings = Income - Expenditure
=> 5x - 19y = 7400.......................... (1)
And 4x - 21y = 3600............................... (2)
Solving both the equations we get x = 3000 and y = 400.
Therefore, the monthly income of Amit is 5x i.e., 15000.
