Answer 1

Answer:

let the income be 9x

let the savings be 4x

then, expenditure = 800+4x

and we know that ,

Income = Saving + Expenditure

9x = 4x + (4x + 800)

9x = 4x + 4x + 800

9x = 8x + 800

9x - 8x = 800

x = 800

we know , here income is 9x

( 9×800 = 7200 )

thus the income of person is 7200
