Question
The savings of I and J are the same. The difference
between J's expenditure and the savings of I and J together equals 0. J's income is Rs. 54,000, and I's expenditure is Rs. 10,000 less than that of J. Calculate I's income.Solution
 Let the savings of I and J be Rs. v each.  Therefore, expenditure of J = Rs. 2v.  Or, 2v + v = 54,000.  Or, v = Rs. 18,000.  Therefore, expenditure of I = 2v – 10,000 = Rs. 26,000.  Income of I = 26,000 + 18,000 = Rs. 44,000.
