Let the number of books on History, Polity and Geography be x, y and z respectively. Given, (x + y + z)/3 = 110 Or, x + y + z = 330 ….. (1) And, (x + z)/2 = 120 Or, x + z = 240 ….. (2) From equation 1 and 2 Number of books on polity = y = 90 Number of books on geography = 0.7 × 90 = 63 Therefore, number of books on history = 330 – (90 + 63) = 177
