      Solution

      Let there are x books in the library. English books = 50% of x= 0.5x Remaining books = x– 0.5x= 0.5x Bengali books = 70% of the remaining books =  70% ×0.5x= 0.35x Tamil books = x- 0.5x - 0.35x = 0.15x Given that, total English books = 5800 0.5x = 5800 x= 11600 Therefore, Tamil books = 0.15x = 0.15 × 11600 = 1740
