When you take the GED, you bring with you the knowledge of what the basic operations are and how to use them. You aren't expected to know the dimensions of some fictional character's room or how well a character does on her reading scores. You're expected to know how to solve problems and to leave the specifics of the problems to the GED test-makers.
Not every question on the GED Math test is solvable. If you come across a question that doesn't include enough information to solve the problem or it can't be answered with the information given, don't panic! Reread the question to make sure it can't be answered and then choose the appropriate answer choice, which is usually "not enough information given" or some variation.
Don't assume that when a question includes the answer choice "not enough information given," it's a clue to mean that you don't have enough information, because some questions that can be solved include this answer choice to make you think. Use this clue only when you've already determined that the question can't be solved.
Here's an example:- Carmen bought a new Thunderbolt 8 as a gift to himself. He was impressed with its shiny aluminum wheels, its all-electronic dashboard, and its ventilated leather seats. The acceleration made him feel like a race car driver. He opted for rustproofing and a deluxe GPS and sound system. He negotiated with the salesperson for several hours to get a monthly payment he could barely afford. What were his annual insurance premiums if he was under 25?
A. $4,159 B. $4,638 C. $5,200 D. not enough information given
This question includes a lot of information; unfortunately, none of it pertains to the question, and Choice (D) is the only answer possible.
