A straight pipe 1 yard in length was marked off in fourths and also in thirds. If the pipe was then cut into separate pieces, at each of these markings, which of the following gives all the different lengths of the pieces, in fractions of a yard?
A. \(\frac{1}{6}\)
B. \(\frac{1}{4}\)
C. \(\frac{1}{12}\)
D. \(\frac{1}{3}\)
E. \(\frac{1}{24}\)
F. \(\frac{2}{3}\)
G. \(\frac{3}{4}\)
A. \(\frac{1}{6}\)
B. \(\frac{1}{4}\)
C. \(\frac{1}{12}\)
D. \(\frac{1}{3}\)
E. \(\frac{1}{24}\)
F. \(\frac{2}{3}\)

Hi
here the solution
Since we want to find the fractions, we can assume some other length of the pipe which will make calculation easier. Take the length of the pipe to be 12-meter long (the least common multiple of 3 and 4.
In this case the branch would be cut at 3, 4, 6, 8, and 9 meters
Distinct lengths would be: 3=3/12=1/4, 4-3=1=1/12 and 6-4=2=2/12=1/6 meters long pieces.
Answer: D.
Why the answer is D Because D encompasses the value contained in the OAs A,B, and C
In other words, this is NOT a GRE question, even though it is legit per se, rather an official GMAT question.
IF jamboree is the source, we do have two options: they steal it or the source is wrong
Regards

Yes, Jamboree is in fact the source. I apologize because I cannot differentiate whether a question is a GRE type.
