# What will the Income of X? If

Incomes of x and y are in the ration 4:3. Their expenditures are in the ratio 12:7. Both save Rs.3200 at the end of the month, then the income of x is:

- Rs.6000
- Rs.8000
- Rs.2000
- Rs.4000

**Answer: (2) Rs.8000**

**Explanation:-**

Let be the income of X is 4A and income of Y is 3A

And, The total expenditure of X & Y be 12B & & 7B

Then,

4A – 12B = 3200 ……………………….. (1)

3A – 7B = 3200 ………………………………. (2)

Solve equation (1) & (2)

B = 400

Put the value of B in equation (1)

4A – 12 x 400 = 3200

4A = 3200 + 4800

4A = 8000

Thus, the income of X = 4A = Rs.8000

Hence, the answer is (2) Rs.8000.
