Copier W prints at a rate of 104 flyers in every 4 minutes and Copier X prints at a rate of 145 flyers in every 5 minutes. At 6 p.m., both copiers started printing. After a while, Copier W stopped printing for some time as the ink cartridges were being changed before it continued to print again. Copier X continued printing during this time. At 9 p.m., the total number of flyers printed during the past three hours was 8839. Express the number of flyers printed by Copier W 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 W prints per min = 104 ÷ 4 = 26
Number of flyers Copier X prints per min = 145 ÷ 5 = 29

From 6 p.m. to 9 p.m. = 3 h
1 h = 60 min
3 h = 180 min

Number of flyers printed by Copier X in 6 h
= 180 x 29
= 5220

Number of flyers printed by Copier W in 6 h
= 8839 - 5220
= 3619

Percentage of the number of flyers that Copier W printed over the total number of flyers printed
= ³⁶¹⁹₈₈₃₉ x 100%
≈ 40.94%

Answer(s): 40.94%
