Let the income be in ratio 9x:7x
Expenditure be 4y:3y
Savings of both is 200 each
Income - Expenditure = Savings
9x - 4y = 200
7x - 3y = 200
9x - 4y = 7x - 3y
y = 2x
So, 9x - 4(2x) = 200
9x - 8x = 200
x = 200
Income = 9x = Rs 1800
= 7x = Rs 1400
Expenditure be 4y:3y
Savings of both is 200 each
Income - Expenditure = Savings
9x - 4y = 200
7x - 3y = 200
9x - 4y = 7x - 3y
y = 2x
So, 9x - 4(2x) = 200
9x - 8x = 200
x = 200
Income = 9x = Rs 1800
= 7x = Rs 1400
