Question

If 'x', 'y' and 'z' are integers, then find whether (x +

Q: Answer-If 'x', 'y' and 'z' are integers, then find whether (x + y - z) is positive or negative. Statement...

ATQ, Statement-I xy2 64 Or, x y 8 5-z2 9 Or, 5 - z 3 z 3 z 28 For, x y 8 For, x y -8 x y - z - 8 - 2 or 8 - 8 -10, -16 So, data in statement I alone is not sufficient to answer the question. Statement II x y - x2 y2 z2 2xy - 2yz - 2zx Or, x y - z x2 y2 z2 2xy - yz - zx Or, x y - z x2 y2 z2 22 As, xy - yz - zx 11 Which is inconclusive So, data in statement II alone is not sufficient to answer the question. Combining statement I and II We cant find the value of x, y and z. So, data given in both statements I and II together are not sufficient to answer the question.

y - z) is positive or negative. Statement I: (x+y)2 = 64 and (5 - z)2 = 9 Statement II : xy - yz - zx = 11 The question consists of two statements numbered "l and II" given below it. You have to decide whether the data provided in the statements are sufficient to answer the question.

A The data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.

B The data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.

C The data either in statement I alone or in statement II alone are sufficient to answer the question.

D The data given in both statements I and II together are not sufficient to answer the question.

E The data in both statements I and II together are necessary to answer the question.
