O 14000​

Answer 1

Step-by-step explanation:

Let the income be x

X income = 9x

Y income = 7x

Let the expenditure be y

X expenditure = 4y

Y expenditure = 3y

as you know,

Income - Expenditure = Saving

For X

9x - 4y = 2000 ------(1)

For Y

7x - 3y = 2000----(2)

Solving both equation simultaneously, you get

x = 2000 , y = 4000

Income of X = 9x = 18000

hope it helps
