Let the number of books on History, Polity and Geography be x, y and z respectively. Given, (x + y + z)/3 = 140 Or, x + y + z = 280 ….. (1) And, (x + z)/2 = 150 Or, x + z = 300 ….. (2) From equation 1 and 2 Number of books on polity = y = 120 Number of books on geography = 0.8 × 120 = 96 Therefore, number of books on history = 420 – (120 + 96) = 204
