Question

Monthly incomes of A and B are in the ratio of 4:3 and their savings are in the ratio of 3:2. If the expenditure of each will be Rs. 600, what will be the monthly income of B​

Answer 1

Answer:

1800 rs.

Step-by-step explanation:

Income of B = 3x

Saving of B = 2x

Expenditure of B = 3x-2x = x = Rs 600

so, Income = 600 x 3 = 1800

Answer 2

Answer:

Step-by-step explanation:

Let their income be 4x and 3x

Let their expenditure be 3y and 2y

We know that , Income − Expenditure = Saving

4x−3y=600 ---(1)

3x−2y=600 ---(2)

On solving (1) & (2)

we get ,

x=600

y=600

Then, the income of A=4 × 600 = Rs.2400

and income of B=3 × 600 = Rs.1800

Hence the monthly income of 'B' is 1,800
