Question

The ratio of income expenditures and Saving of a and b 2:1 ,5:3,4:1 respectively if the total saving of A and B is 25000 then find out income of A

Answer 1

Step-by-step explanation:

Solution:

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
