So that the income of Company Y in 1996 = Rs. (342 - z) crores. Then, for Company X we have: 40 = z - x x 100 40 = z - 1 x = 100z .... (i) x 100 x 140 Also, for Company Y we have: 45 = (342 - z) x 100 45 = (342 - z) - 1 x = (342 - z) x 100 .... (ii) x 100 x 145 From (i) and (ii), we get: 100z = (342 - z) x 100 z = 168. 140 145 Substituting z = 168 in (i), we get : x = 120. Total expenditure of Companies X and Y in 1996 = 2x = Rs. 240 crores. Total income of Companies X and Y in 1996 = Rs. 342 crores. Total profit = Rs. (342 - 240) crores = Rs. 102 crores.
