Question
The savings of E and F are identical. The difference
between F's expenditure and the combined savings of E and F is zero. B's income is Rs. 36,000, and E's expenditure is Rs. 7,000 less than F's. What is E's income?Solution
 Let the savings of E and F be Rs. z each.  Therefore, expenditure of F = Rs. 2z.  Or, 2z + z = 36,000.  Or, z = Rs. 12000.  Therefore, expenditure of E = 2z – 7,000 = Rs. 14,000.  Income of E = 14000 + 12,000 = Rs. 26,000.
