Question 1 · Multiple choice

Question

A team of three students, Alex, Blake, and Casey, are tasked with labeling 1,500 envelopes. Alex labels 25 envelopes per hour for 12 hours. Blake then labels 30 envelopes per hour for 15 hours. Casey finishes the rest. What fraction of the total envelopes did Casey label?

Options

  • A. 1/2
  • B. 11/30
  • C. 1/3
  • D. 7/15
  • E. 1/4

Correct answer

A. 1/2

Explanation

Alex: 25 * 12 = 300. Blake: 30 * 15 = 450. Total so far: 300 + 450 = 750. Remaining for Casey: 1500 - 750 = 750. Fraction: 750/1500 = 1/2.

Question 2 · Multiple choice

Question

The average height of a group of six students is 152 cm. A new student joins the group, and the average height increases to 153 cm. How tall is the new student?

Options

  • A. 153 cm
  • B. 156 cm
  • C. 159 cm
  • D. 162 cm
  • E. 165 cm

Correct answer

C. 159 cm

Explanation

Total height of 6: 152 * 6 = 912. Total height of 7: 153 * 7 = 1071. New student: 1071 - 912 = 159 cm.
