Each of the questions below consists of a question and three statement

1.	Each of the questions below consists of a question and three statements number I, II and III given below it. You have to decide whether the data provided in the statement are sufficient to answer the question.Find the value of x?Statement I. 4xyz + 2y + 4 – 34z = 0, z = 1Statement II. y = \(\sqrt {428 - 419} \)Statement III. xyz – 3z + 8y – 9 = 0, z = -1.1. Either statement I and II together or Statements I and III together is sufficient to answer the question.2. The data in statement I alone or statements II and II together is sufficient to answer the question.3. The data in any two of the three statements is sufficient to answer the question.4. The data in all the statements I, II, and III are not sufficient to answer the question.5.The data in all statements I, II, and III together are necessary to answer the question.
Answer» Correct Answer - Option 3 : The data in any two of the three statements is sufficient to answer the question. Calculation: Statement I: 4xyz + 2y + 4 – 34z = 0, z = 1 ⇒ 4xy + 2y + 4 – 34 = 0 ⇒ 4xy + 2y – 30 = 0 Statement II: y = \(\sqrt {428 - 419} \) ⇒ y = 3 Statement II: xyz – 3z + 8y – 9 = 0, z = -1. ⇒ -xy + 3 + 8y – 9 = 0 ⇒ 8y – xy – 6 = 0 We will receive the value of x with the help of any two statements.

Answer» Correct Answer - Option 3 : The data in any two of the three statements is sufficient to answer the question.

Calculation:

Statement I:

4xyz + 2y + 4 – 34z = 0, z = 1

⇒ 4xy + 2y + 4 – 34 = 0

⇒ 4xy + 2y – 30 = 0

Statement II:

y = \(\sqrt {428 - 419} \)

⇒ y = 3

Statement II:

xyz – 3z + 8y – 9 = 0, z = -1.

⇒ -xy + 3 + 8y – 9 = 0

⇒ 8y – xy – 6 = 0

We will receive the value of x with the help of any two statements.
