# GRE Quantitative Practice, Numeric Entry

*Question 1*

Assume that *x* > 5 and that 2*x* is a multiple of 5. If 2*x* + 1 < 100, how many values for *x* are possible?

ENTER A NUMBER IN THE BOX:

## Explanatory Answer

Given that 2*x* is a multiple of 5, *x* must be a multiple of 2.5. Given *x* > 5 and 2*x* + 1 < 100, the least value of *x* is 7.5 and the greatest value of *x* is 47.5. That leaves 17 possibilities for the value of *x*. To gain credit for answering the question correctly you would need to enter the number 17 in the numeric-entry box.
