Answer» Correct Answer - Option 1 : 20, 10 and 300 Given: Let the number of floors are 2x and x (2x + x)/2 = 15 X = 10 number of floors in tower A = 20 Number of floors in tower B = 10 Number of houses on each floor of tower A = (1/2) of 20 = 10 Total number of houses in tower A = 10 × 20 = 200 Number of houses on each floor of tower B = (1/2) of 20 = 10 Total number of houses in tower B = 10 × 10 = 100 Total number of houses in both the towers = 200 + 100 = 300 |
