It is given that;

(1) Those 8 members of the family belong to three different generations.

(2) There are three married couples and two persons are unmarried in the family.

(3) Each married couple has at least a child.

From the above three conditions, we get the following two possibilities.

Here, the family members are denoted by F1, F2,…., F8.

Let us consider possibility (I):

It is given that V and R are the only siblings.

Thus, let us consider F3 as V and F4 as R.

V has a daughter 8, thus F7 is S.

Therefore, U, W, R and S are females.

The person who works with C is the maternal grandfather of Q.

Therefore, F8 is Q, who works with D. Let F1 works with C.

It is given that R works with B.

The person who works with A is the mother of the person, who works with F and both are females.

The only possibility is that F5 (wife of V) works with A and her daughter works with F.

Since, the person working with G and E belong to the same generation, V works with E, which violates a condition.

Therefore,  this case is not possible.

Consider possibility ([1):

Here again we have two cases:

Case (a) :

When F2 is R.

In this case, F3 is V and F, is the person who works with C.

F6 is S and F8 is Q.

F4 is U, who works with A and thus F6 works with 8.

Therefore, F7 and F5 will be working in E and G respectively.

=> V will be working with H, which is not possible.

Therefore, This case is not possible.

Case (b) :

When F2 is V.

F3 is R and V works with C.

F5 is S and F8 is Q and works with D.

W is not the couple of V.

Since, W is a female, she can’t be F4 or F7 (as both are males).

Therefore, F6 is W.

=> F1 is U and works with A and thus S works with F.

As the persons working with G and E belong to the same generation, the only possibility is that W works with G and F7 works with E.

=> F4 works with H.

Therefore, F4 is T and F7 is P.

The final arrangement is as follows:

Q1. W works with G. Choice (2)

Q2. S is the wife of the person who works with E. Choice (2)

Q3. Both V and U as well as R and T are married couples. Choice (4)

Q4. Only choice (1) is true. Choice (1)
