Question

Your last science test has 35 questions and is worth 100 points. the test is broken up into two parts; part 1 has questions worth 2 points each and part 2 has questions worth 4 points each. how many questions are in each part of the test?

Answer 1

Total questions = 35

Assumed all 35 are 2 points
⇒ 35 x 2 = 70

Difference in points
⇒ 100 - 70 = 30

Number of 4 points questions = 30 ÷ 2 = 15
Number of 2 points questions = 35 - 15 = 20

Answer: There are 15 4-points questions and 20 2-points questions.
