Question

Monthly income of A and B are in the ratio 9:11 and those of B and C are in the ratio 13:10 if monthly income of C ₹1430 find incomes of A and B?

Answer 1

The incomes of A and B are in the ratio 9:4 and their expenditures are in the ratio 7:3. If each saves ₹2000, what are their incomes?

Let,

Income of A = 9x

Income of B = 4x

Expenses of A = 7x

Expenses of B = 3x

A & B both saves ₹2000

then we find the value of x through this eq.

(9x-2000)/(4x-2000) = 7/3

27x-6000 = 28x-14000

x = 8000

Now put the values and find INCOME

Income of A = 9x = 9*8000 = ₹72000

Income of B = 4x = 4*8000 = ₹32000
