Numbers
All numbers used are real numbers.

Figures
A figure accompanying a data sufficiency question will conform to the information given in the question but will not necessarily conform to the additional information given in statements (1) and (2).

Lines shown as straight can be assumed to be straight and lines that appear jagged can also be assumed to be straight.

You may assume that the positions of points, angles, regions, etc. exist in the order shown and that angle measures are greater than zero.

All figures lie in a plane unless otherwise indicated.

Q.
What is the standard deviation (SD) of the four numbers p, q, r, s?
  1. The sum of p, q, r and s is 24
  2. The sum of the squares of p, q, r and s is 224
  • a)
    Statement (1 ) ALONE is sufficient, but statement (2 ) alone is not sufficient to answer the question asked.
  • b)
    Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.
  • c)
    BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.
  • d)
    EACH statement ALONE is sufficient to answer the question asked.
  • e)
    Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
NumbersAll numbers used are real numbers.FiguresA figure accompanying ...
From statement 1 we know that the square of the means is 36.
From statement 2 we know that the mean of the squares is 56.
Using the formula, Standard deviation = 

we can find the SD of the 4 numbers
Statements TOGETHER are SUFFICIENT.
Choice C is the answer.
