Even though i selected E,
just wanted to ask
if there were brackets is when we consider it meant 1/4 (x-5) and if not its actually x/4 -5
vksunder
If x is to be selected at random from T, what is the probability that \(\frac{1}{4}*x-5\leq{0}\)?
(1) T is a set of 8 integers.
(2) T is contained in the set of integers from 1 to 25, inclusive.
Yes, you're correct. Without brackets, 1/4*x - 5 means x/4 - 5. Brackets around (x - 5) would change it to 1/4(x - 5).
P.S. Pure algebraic questions are no longer a part of the
DS syllabus of the GMAT.
DS questions in GMAT Focus encompass various types of word problems, such as:
- Word Problems
- Work Problems
- Distance Problems
- Mixture Problems
- Percent and Interest Problems
- Overlapping Sets Problems
- Statistics Problems
- Combination and Probability Problems
While these questions may involve or necessitate knowledge of algebra, arithmetic, inequalities, etc., they will always be presented in the form of word problems. You won’t encounter pure "algebra" questions like, "Is x > y?" or "A positive integer n has two prime factors..."
