Let the incomes in 2000 of Companies X and Y be 3x and 4x respectively. And let the expenditures in 2000 of Companies X and Y be E1 and E2 respectively. Then, for Company X we have: 65 = 3x - E1 x 100 65 = 3x - 1 E1 = 3x x 100 .... (i) E1 100 E1 165 For Company Y we have: 50 = 4x - E2 x 100 50 = 4x - 1 E2 = 4x x 100 .... (ii) E2 100 E2 150 From (i) and (ii), we get: E1 = 3x x 100 165 = 3 x 150 = 15 (Required ratio). E2 4x x 100 150 4 x 165 22
