Analytical Ability

In questions numbered 1 to 20 , a question is followed by data in the form of two statements labelled as I and II. You must decide whether the data given in the statements are sufficient to answer the questions. Using the data make an appropriate choice from (1) to (4) as per the following guidelines:

Question : 8 of 200

Marks: +1, -0

Z_{1}

and

Z_{2}

are complex numbers. Is

Z_{1}+Z_{2}

real

?

I) The real and imaginary parts of

Z_{1}

and

Z_{2}

are integers
II)

Z_{1}

is conjugate of

Z_{2}

Mark choice (1) if the statement I alone is sufficient to answer the question.
Mark choice (2) if the statement II alone is sufficient to answer the question.
Mark choice (3) if both the statements I and II are sufficient to answer the question but neither statement alone is sufficient.
