Question: 607

1. In a jar of lollipops, the ratio of red lollipops to blue lollipops is 3:5. If only red lollipops and blue lollipops are in the jar and if the total number of lollipops in the jar is 56, how many blue lollipops are in the jar?

  • A. 35
  • B. 28
  • C. 21
  • D. 8

Correct Answer: A

Explanation:

When the question asks about ratios, make a Ratio Box. The ratio of red to blue lollipops is 3:5, so place this information in the ratio row. Add across to find that 3 + 5 = 8, and put 8 in the total column for this row. The question states that the total number of lollipops is 56. Put this number in the total column in the actual number row. Now, ask yourself what times 8 equals 56. Well, 7 × 8 = 56, so the multiplier is 7. To find the number of blue lollipops, multiply 5 × 7 = 35. The correct answer is (A).
