A. (p+n)/2 B. (p−n)/2 C. p−n
D. p−2n E. (p+2n)/2 Solution • As per the given conditions
o \(A + B = p\) ……………..(i)
o \(A = n + B\)
o \(A – B = n\) ………..(ii) • Adding equation (i) and (ii), we get
o \(2A = p + n\)
o \(A = \frac{(p+n)}{2}\) • Thus, the correct answer is Option A. Thanks, Saquib Quant Expert eGMATRegister for our Free Session on Number Properties (held every 3rd week) to solve exciting 700+ Level Questions in a classroom environment under the realtime guidance of our Experts

A. (p+n)/2 B. (p−n)/2 C. p−n
D. p−2n E. (p+2n)/2 Or just plug in values. Say they both have been published 10 times (p = 10) and Alexa has been published 10 times more i.e. Brent has been published 0 times. We need the option that gives 10 when p = n = 10 Only (A) does that.

A. (p+n)/2 B. (p−n)/2 C. p−n
D. p−2n E. (p+2n)/2 Let A and B denote the number of times Alexa and Brent has been published, respectively. Since they have been published p times, A + B = p. Since the number of publications of Alexa is n more than Brent, A = B + n. Let’s write the second equality as B = A  n. Let’s substitute this expression for B in the first equation: A + (A  n) = p 2A = p + n A = (p + n)/2 Answer: A

Please clarify. Thanks Hi manishtank1988 , Between them, they have been published p times, with Alexa having been published n times more than Brent has . A = b+n (since Alexa having been published n times more than Brent has  we add here ) If question was that Alexa was published n times the number of times Brent was published, then A = b*n is correct B = b 2b+n = p => b = (pn)/2 A = (pn)/2 +n = (p+n)/2 Answer A Hope this helps!!

Let A be the times Alexa has been published and let B be the times Brent has been published. They have been published p times i.e. A+B = p Now, Alexa has been published n times more than Brent. > A= B+n > B = A  n Substituting value of B in original equation. A+An = p > 2A = p+n > A=(p+n)/2 Answer A. Sent from my SMN9007 using GMAT Club Forum mobile app

Yes, but you are answering WRONG question. The question asks: Which of the following represents the number of times that Alexa has been published? You found the number of times that Brent has been published: B = (p  n)/2. Hope it's clear.
