Copier E prints at a rate of 118 flyers in every 2 minutes and Copier F prints at a rate of 144 flyers in every 6 minutes. At 3 p.m., both copiers started printing. After a while, Copier E stopped printing for some time as the ink cartridges were being changed before it continued to print again. Copier F continued printing during this time. At 5 p.m., the total number of flyers printed during the past two hours was 7259. Express the number of flyers printed by Copier E 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 E prints per min = 118 ÷ 2 = 59
Number of flyers Copier F prints per min = 144 ÷ 6 = 24

From 3 p.m. to 5 p.m. = 2 h
1 h = 60 min
2 h = 120 min

Number of flyers printed by Copier F in 3 h
= 120 x 24
= 2880

Number of flyers printed by Copier E in 3 h
= 7259 - 2880
= 4379

Percentage of the number of flyers that Copier E printed over the total number of flyers printed
= ⁴³⁷⁹₇₂₅₉ x 100%
≈ 60.33%

Answer(s): 60.33%
