The following question has three statements I, II and III. You have to decide whether the data given in the statement is sufficients to answer.

Read the statements carefully and choose the correct option.

How many sons of X?

Statements :

I. Q and U are brother of T

II. R is sister of P and U

III. R and T are daughter of X

I, II and III together are not sufficient

The statements I, II, and III provide information about relationships between individuals, but they do not provide enough information to determine the number of sons of X.

Statement I only tells us that Q and U are brothers of T, but it does not provide any information about X.

Statement II only tells us that R is sister of P and U, but it does not provide any information about X.

Statement III only tells us that R and T are daughters of X, but it does not provide any information about the number of sons of X.

Thus, we need more information to determine the number of sons of X.
