What is the value of $ x^{2}+y+z? $ I. $ 4x+3y+5z=60, $ $ 2x=y, $ $ 2y=z $ II. $ 3x+3y+2z=34, $ $ 2x+5y+6z=72 $
A) If 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) If 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) If the data in either statement I alone or in statement II alone are sufficient to answer the question
D) If the data in both the statements I and, II are not sufficient to answer the question
E) If the data in both the statements I and II together are necessary to answer the question
Correct Answer: A
$ \therefore $ $ x^{2}+y+z={{(2)}^{2}}+4+8=16 $ … (ii) From Statement II, $ 3x+3y+2z=34 $ and $ 2x+5y+6z=72 $ … (iii) We cannot find the values of x, y and z from Eqs. (ii) and (iii).
