    Question

    Answer the questions based on the information given below: Eight persons namely A, B, C, D, E, F, G and H lives in eight different floored building. Floors of building are marked 1 to 8 in such a way that floors are marked from bottom to top. Each person was born in different year viz. 1985, 1993, 1978, 1995, 1997, 1994, 1998 and 1989. All the information is not necessary in same order. Age of the person is calculated from current year 2020. B lives on any floor below the one who was born in 1993. Number of person below the F is one third the number of person below the one whose age is 25 years. At least one person lives between B and the one whose age is 27 years. Only two person lives between the one whose age is 25 years and B, whose age is not 27 years. Sum of ages of the one who lives on floor 2 and B is 53 years. Two person lives between E and the one who was born in 1993. Average sum of ages of the one who lives on lowermost floor and G is one more than the age of D. E, whose age is not odd number, lives just above the one whose age is multiple of five. H does not live even numbered floor, was neither born in 1985 nor is his age is an even number. Age of D is neither odd number nor he lives below A. Number of person below E is two more than number of person above A. Age of B is greater than G. More than two floor between C and D. The one whose age is 25 years do not live in odd numbered floor.

    Who lives in fourth floor and the age of that person

    is?
    A G, 31 Correct Answer Incorrect Answer
    B E, 22 Correct Answer Incorrect Answer
    C C, 25 Correct Answer Incorrect Answer
    D A, 25 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    First Calculate age as shown in figure Number of person below the F is one third the number of person below the one whose age is 25 years. The one whose age is 25 years do not live in odd numbered floor. Only two person lives between the one whose ageis 25 years and B, whose age is not 27 years. At least one person lives between B and the one whose age is 27 years. Sum of ages of the one who lives on floor 2 and B is 53 years. B lives on any floor below the one who was born in 1993. Age of B is greater than G Brief hints: 2 possibilities to make 53 (31, 22) & (27, 26) è In case-1 (27, 26) combination is not possible for B and 2 nd floor Note: If B’s age is 22 and then G’s age must be less than 22 years which is not possible as per age calculation table. Hence B’s age must be 31 years and F’s age must be 22 years Two person lives between E and the one who was born in 1993. E, whose age is not odd number, lives just above the one whose age is multiple of five. At least one person lives between B and the one whose age is 27 years. Number of person below E is two more than number of person above A. Age of D is neither odd number nor he lives below A. More than two floor between C and D. H does not live even numbered floor, was neither born in 1985 nor is his age is an even number.
