Age of B is double the age of F. None of them lives at the third floor. Ages of F and G are 24 and 60 respectively. Age of the person living at 7 th floor is 50 and the age of the person living at 3 rd floor is 20. Using the first hint we can find out the age of B with respect to F. And after using the second hint we can say that the ages of F and G are 24 and 60 respectively. But we already have a hint that age of B is twice the age of F. So, now we can say that the age of B is 48. E lives just below the floor at which B lives and just above the floor at which F lives. E does not live at 3 rd floor. Age of E is equal to the average of sum of the ages of G and A and the age of E is 40. Using the first hint we can say that there is only one possible scenario in which we can fix the positions of B, E and F under the given conditions. This is shown in the table given below
Now, with the second hint ⇒ E = (G + A)/2 It is given that the age of E is 40 years. ⇒ 40 = (60 + A)/2 ⇒ A = 20 years Therefore, the age of A is 20 years and we know that the person whose age is 20 lives on the 3 rd floor. So, we can say that A lives on 3 rd floor F, E, B, G do not live at the 1 st floor. Age of the person living at the 2 nd floor is one more than the age of the person living at 1 st floor. With the first hint we can say that G does not lives on the 1 st floor and we know that G cannot live on 7 th floor either as the person whose age is 50 lives on 7 th floor and the age of G is 60. So, now there is only one floor left for G to lives i.e. 2 nd floor. Using the second hint we can figure out that the age of the person who lives on 1 st floor is 59.
