Direction: Read the following information carefully and answer the questions.
A group of 10 people Arti, Aradhya, Akansha, Aasha, Arya, Bharti, Bhawana, Bidya, Bibha&Babita work in the same company but in 10 different floors. The floors are numbered from 1 to 10 and the lowest floor is numbered as 10 and the topmost floor as 1. They live according to their ages which are between 19 to 35 years.
Babita whose age is an even number works on one of the even floors below 5 and above 10. The age gap between Bidya&Bibha is half of the age gap between Arti and Bidya.Arti is 10 years younger than Bidya. Bhawana who is an immediate neighbour of Arti works on one of the floors above Aradhya. The age gap between Akansha and Arya is 5 years. The number of girls working below Arti is the same as the number of girls working above Bibha. Bhawana is the youngest member and the age gap between her and Arya is 1 year. Bidya whose age is an odd multiple of 11 works on the 3 floors above Bharti. Aasha works immediately above Bibha and her age is a multiple of 17. Arya works on the 5th floor andthere are three floors are between her andArti. Akansha’s age is a multiple of 13 and she works on one of the odd floors above 5th floor but none of them works on the topmost floor. The age of the girl who works on the 7th floor is an odd multiple of 5. The age gap between the oldest member and Babita is a cube root of 64.The age of the girl who works on the 6th floor is a prime number that lies between 23 & 31.
What is the age of Arya?
1) Arya works on fifth 5th floor & 3 girls work between her &Arti.
2)The age of the girl who works on the 7th floor is an odd multiple of 5.
So, the age of the girl who works on the 7th floor is 25 years as 20, 30 are not possible.
3) The number of girls working below Arti is the same as the number of girls working above Bibha.
4) Akansha’s age is a multiple of 13 and she works on one of the odd floors above 5th floor but none of them works on the topmost floor.
So, Akansha’s age is 26 years
Therefore, two cases are possible here.
Case - 1
Floor No.

Age
Arti
Akansha

25
Bibha
Case - 2
5) The age gap between Akansha and Arya is 5 years.
So, Arya’s age is 21 years or 31 years]
6) The age of the girl who works on the 6th floor is a prime number that lies between 23 & 31.
Age of girl who works on the 6th floor is 29 years.
7) Aasha works immediately above Bibha and her age is a multiple of 17.
So, Aasha’s age is 34 years
8) Babita whose age is an even number works on one of the even floors below 5 and above 10.
9) The age gap between the oldest member and Babita is a cube root of 64.
So, Babita’s age is 30 years; Babita’s age = Aasha’s age – 4; Babita’s age = 34 - 4
10) Bidya whose age is an odd multiple of 11 works on the 3 floors above Bharti.
So, Bidya’s age is 33 years.

3) Bhawana who is an immediate neighbour of Arti works on one of the floors above Aradhya.
Here we eliminate the case 2.
6) Bhawana is the youngest member and the age gap between her and Arya is 1 year.
So, Bhawana’s age is 20 years & Arya’s age is 21 years.
2) The age gap between Bidya&Bibha is half of the age gap between Arti and Bidya. Arti is 10 years younger than Bidya.
So, Arti’s age is 23 years &Bibha’s age is 28 years
23

So, Arya is 21 years old.
Bhawana lives on which of the floors?
So, Bhawana lives on the 2nd floor.
Who lives on the 9th floor?
So, Aasha lives on the 9th floor.
Whose is 33 years old?

The ground floor is numbered Floor-1 and the top floor is Floor- 4. Flat – 1 of Floor – 2 is just above Flat – 1 of Floor – 1 and just below Flat-1 of Floor – 3 and so on. Only the persons who are mentioned below are considered to be living in the building.
The number of persons on the topmost floor is double the number of persons on the bottommost floor. The number of persons is living on the floor – 3 is more than the number of persons are living on the floor – 1 but less than the number of persons are living on floor – 4. The number of persons are living on the topmost floor is one more than the number of persons are living on the second floor. No flat is vacant in the building. Each floor having a different number of persons living in it.
D is living on even number floor and he is immediately east of G. E is living immediately below D in the same flat number. B is living immediately to the east of E. H is living below C in the same flat number and both live on even number floor. No one lives with C and H in the same flat. N is living alone in flat immediately below Q, who lives with only R. F is to the northeast of N.
