Question : 90

Total: 150

F is in the same branch with?

Validate

Solution:

Ten friends: A, B, C, D, E, F, J, K, L and M.
Three branches: B.sc, B.com and B.A.
1) A and B in the same branch but not in the B.com. A and B are not in B.com so they will be either in the B. A. or in the B.sc, now we have two cases for A and B.
Case 1.

Branches	B.sc	B.com	B.A.
Friends	A, B

Case 2.

Branches	B.sc	B.com	B.A.
Friends			A, B

2) D and C are in the different branch but not in the B.com. C does not study with A.
Case 1.

Branches	B.sc	B.com	B.A.
Friends	A, B, D		C

Case 2.

Branches	B.sc	B.com	B.A.
Friends	C		A, B, D

3) L studies with two more friends in the B.A. Here it is fixed that there three friends in B. A. so possibility of A, B and D in the B. A. is canceled here, now we continue with A, B and D in the B.sc,

Branches	B.sc	B.com	B.A.
Friends	A, B, D		C, L

4) K is neither in the same branch with A nor studies in the B.com,

Branches	B.sc	B.com	B.A.
Friends	A, B, D		C, L, K

5) F is neither in the same branch with A nor with J. F is in the branch having more than three students but not in the B.com.

Branches	B.sc	B.com	B.A.
Friends	A, B, D		C, L, K, F

6) J study with two more friends but not in the B.A. J and K are in the different branch and neither of them is in the same branch with D.

Branches	B.sc	B.com	B.A.
Friends	A, B, D	J	C, L, K, F

7) E is not in the same branch with B or C, so E will be in B.com.

Branches	B.sc	B.com	B.A.
Friends	A, B, D	J, E	C, L, K, F

8) M is neither in the same branch with F nor with the D, so M will be in the B.com. Now the final arrangement is as follows;

Branches	B.sc	B.com	B.A.
Friends	A, B, D	J, E, M	C, L, K, F

Hence, 'F' is in the same branch with 'C'.
