What is the value of (3+ 2p)/ (3p) ?
(1) p^2 – 5p + 4 = 0.
(2) The value of (1/p)+(2/3) is –2.
Dear
vikasp99,
I'm happy to respond.
I don't know the source, but this is a particularly easy question. Furthermore, I don't think it is a question of high quality.
The details of the prompt are irrelevant: to answer the prompt question, we simply need the value of p.
Statement #1:
\(p^2 – 5p + 4 = 0\)This quadratic is not a perfect square, so it has two solutions. Two values for p will not determine a unique answer to the prompt. This statement, alone and by itself, is
not sufficient.
Statement #2:
The value of (1/p)+(2/3) is –2In other words,
\(\frac{1}{p} + \frac{2}{3} = –2\)
We have an equation. We can solve for the unique value of p. This is
sufficient. The fact that the left side of this equation is a re-written form of the prompt expression is simply irrelevant to solving the DS question.
OA =
(B) Here's a more challenging DS question.
Fraction question Does all this make sense?
