Question

If the incomes of a and b are in the ratio 5:4 and their expenses are in the ratio 14:11. if both a and b save rs.1000. what is a's income?

Answer 1

Let income of A and B be 3x and 2x respectively. Also, their expenditure is 5y and 3y.

Now, according to question,

3x-5y = 1000 ------- (i)*3

2x-3y = 1000 ---------- (ii)*5

9x-15y-10x+15y = 3000-5000;

Or, -x = -2000;

Or, x = 2000;

Then, income of A = 3x = 3*2000 = Rs. 6000.
