  • Question

  • What is the value of p2 + q + r?
    I. 4p + 3q + 5r = 60, 2p = q, 2q = r
    II. 3p + 3q + 2r = 34, 2p + 5q + 6r = 72


  • Options
  • 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

  • Correct Answer
  • 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 

    Explanation

    From Statement I , given that
    4p + 3q + 5r = 60...............(i)
    2p = q
    ? p = q/2 ................(ii)
    and 2q = r ....................(iii)
    putting the value of p and r in terms of q in Eq. (i),
    4 x q/2 + 3q + 5 x 2q = 60
    15q = 60
    ? q = 4
    put the value of q in Eq. (ii)
    ? p = q/2 = 4/2
    p = 2;
    put the value of q in Eq. (iii)
    ? r = 2q = 2 x 4
    ? r = 8
    ? value of p2 + q + r = (2)2 + 4 + 8 = 16
    From Statement II,
    3x + 3y + 2z = 34 ..............(a)
    and 2x + 5y + 6z = 72 ....(b)
    We cannot find the value of p, q and r from Eqs. (a) and (b)
