Question
The average number of novels on historical, thriller and
fantasy in a library is 120, and the average number of novels on historical and fantasy is 110. If the number novels on fantasy is 15% less than the number of novels on thriller, then what is the number of novels on historical in the library?Solution
Let the number of novels on historical, thriller and fantasy be x, y and z respectively. Given, (x + y + z)/3 = 120 => x + y + z = 360 ….. (1) And, (x + z)/2 = 110 => x + z = 220 ….. (2) From equation 1 and 2 Number of novels on thriller = y = 140 Number of novels on fantasy = 0.85 × 140 = 119 Therefore, number of novels on historical = 360 – (140 + 119) = 101
