Copier C prints at a rate of 81 flyers in every 3 minutes and Copier D prints at a rate of 150 flyers in every 6 minutes. At 5 p.m., both copiers started printing. After a while, Copier C stopped printing for some time as the ink cartridges were being changed before it continued to print again. Copier D continued printing during this time. At 8 p.m., the total number of flyers printed during the past three hours was 8067. Express the number of flyers printed by Copier C as a percentage of the total number of flyers printed by both copiers. Round off your answer to 2 decimal places.
Number of flyers Copier C prints per min = 81 ÷ 3 = 27
Number of flyers Copier D prints per min = 150 ÷ 6 = 25

From 5 p.m. to 8 p.m. = 3 h
1 h = 60 min
3 h = 180 min

Number of flyers printed by Copier D in 5 h
= 180 x 25
= 4500

Number of flyers printed by Copier C in 5 h
= 8067 - 4500
= 3567

Percentage of the number of flyers that Copier C printed over the total number of flyers printed
= ³⁵⁶⁷₈₀₆₇ x 100%
≈ 44.22%

Answer(s): 44.22%
