Here plugging in helps...start with option c for possible x value and see which value satisfies the given equation Or you can form an equation x/4= x/8+2 > x= 16 Note that x/4 = 2x/8 and thus x/8= 2 from the above equation and hence x= 16... Ans C Posted from my mobile device

The direct approach would be like this: x/4 = x/8 + 2 x/4  x/8 = 2 (8x4x) = 64 4x = 64 x=16
(C) is the answer.

If x/4 is 2 more than x/8, then x =
(A) 4 (B) 8 (C) 16 (D) 32 (E) 64
Used Option Choices: Option 1, 2 can't be the answer as X/8 gives half and one. Option 3 x/4 is 2 more than x/8== 16/4 = 16/8 +2 ==>>> 4= 4 option 4 32/4= 32/8+2 incorrect Option 5 64/4 = 64/8 +2 incorrect.
Thanks, AB
+1 Kudos If you like and understand.

Let y = x/8.
So, 2y = x/4
Rewriting the equation (x/4)  (x/8) = 2 as 2y  y = 2, we get y = 2 Or, x/8 = 2 Or, x = 16
Hence, answer is option (C).

This is an Algebra, Linear Equations problem. Such kind of sums need extra attention while setting up the equations and most of the options are trap answers from wrong setup. he correct setup is : x/4 + 2 + x/8. x/4x/8=2 Here, if you realize that x/8 is actually half of x/4 then u directly have, x/8=2 and therefore, x=16.

One of the best way of solving such questions is checking the options.... (C) \(x = 16\) \(\frac{x}{8} = 2\) \(\frac{x}{4} = 4\) Where \(\frac{x}{4}\) is 2 more than \(\frac{x}{8}\)... Thus, correct answer must be (C) 16

\(\frac{x}{4}=\frac{x}{8}+2\) \(\frac{x}{4}\frac{x}{8}=2\) \(\frac{x}{8}=2\) \(x=16\) Answer C

The direct approach would be like this: x/4 = x/8 + 2
x/4 = (x + 16)/8
x/1 = (x+ 16)/2
2xx = 16
x=16

[quote="Bunuel"] The Official Guide For GMAT® Quantitative Review, 2ND EditionIf x/4 is 2 more than x/8, then x = (A) 4 (B) 8 (C) 16 (D) 32 (E) 64 Solution : Easy approach for these questions where denominators are multiples of one another x/4 can be rewritten as 2x/8. This helps to reduce the time for solving So equuation can be changed as 2x/8 = 2 + x/8 So x/8 = 2 or x = 16 Answer : C Please give +1 Kudos if you like this approach
