Copier W prints at a rate of 108 flyers in every 2 minutes and Copier X prints at a rate of 120 flyers in every 6 minutes. At 4 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 8 p.m., the total number of flyers printed during the past four hours was 8283. 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 = 108 ÷ 2 = 54
Number of flyers Copier X prints per min = 120 ÷ 6 = 20

From 4 p.m. to 8 p.m. = 4 h
1 h = 60 min
4 h = 240 min

Number of flyers printed by Copier X in 4 h
= 240 x 20
= 4800

Number of flyers printed by Copier W in 4 h
= 8283 - 4800
= 3483

Percentage of the number of flyers that Copier W printed over the total number of flyers printed
= ³⁴⁸³₈₂₈₃ x 100%
≈ 42.05%

Answer(s): 42.05%
