In Unitech cyber-park, there are two buildings of residential flats – tower A and tower B. The number of flats in tower A is less than 100 while that in tower B is not less than 75. For each tower, flats are classified into two categories – 2BHK or 3BHK. A 2BHK flat requires not more than two rooms, while a 3 BHK flat requires three or more rooms. Further a flat could be of X type or Y type (flat located at less than 6th floor). The number of 3BHK Y type flats in tower B is 10 less than half the number of 2BHK type Y flats in tower A. The ratio of number of 2BHK X type flats in tower A to number of 3BHK type X flats in tower B is 5: 3. The number of type Y 3BHK flats in tower A is 5 less than thrice the number of type X 2BHK flats in tower B. The number of type X flats in tower B is 35 less than the number of 2BHK flats in tower A. The number of type Y flats in tower A is 30 more than the number of 3BHK flats in tower B. The number of 2BHK type Y flats in tower B is thrice the number of type X 3BHK flats in tower A. Number of 3BHK flats of type Y in tower B is at least 5.
