A bank of 246 exam style questions for GED candidates. Every answer comes with a four part rationale: why the correct answer is right, why the others are wrong, the principle behind it, and the takeaway to remember.
Answer: A. Correct: 36, because 30 percent of 120 is 0.30 times 120, which equals 36. Why the other choices are wrong: they miscompute the percentage. Principle: percent of a number multiplies the decimal by the number. Takeaway: 30 percent of 120 is 36.
Sample question 2. MATH: Solve: 5x = 45. x = ?
A. 11
B. 9
C. 7
D. 5
Answer: B. Correct: 9, because dividing both sides of 5x = 45 by 5 gives x = 9. Why the other choices are wrong: 5, 7, and 11 do not satisfy 5 times x equaling 45. Principle: isolate the variable by doing the inverse operation to both sides. Takeaway: divide both sides by the coefficient to solve a one step equation.
Sample question 3. MATH: The area of a rectangle 4 by 6 is:
A. 48
B. 10
C. 24
D. 20
Answer: C. Correct: 24, because the area of a rectangle is length times width, and 4 times 6 is 24. Why the other choices are wrong: 10 adds the sides, 20 is incorrect, and 48 doubles the area. Principle: rectangle area equals length multiplied by width. Takeaway: multiply length by width to get a rectangle's area.
