Answer 1

Answer:

Step-by-step explanation:

Consider incomes of A = 7x

and that of B= 5x

Consider expenditure of A = 3y

and that of B= 2y

Now Savings = Income - Expernditures

As it is given that both of them Save Rs ‘R’ so their savings is equal

Savings of A = Saving of B

7x - 3y = 5x - 2y

2x = y …………………… 1

Now Savings of A = 7x - 3y = R

Substituting value of y = 2x from 1

7x - 3*2x = R

7x - 6x = R

x = R

y = 2R

Now we can get income of A in terms of R which is
