Copier F prints at a rate of 90 leaflets in every 3 minutes and Copier G prints at a rate of 120 leaflets in every 4 minutes. At 4 p.m., both copiers started printing. After a while, Copier F stopped printing for some time as the ink cartridges were being changed before it continued to print again. Copier G continued printing during this time. At 6 p.m., the total number of leaflets printed during the past two hours was 8733. Express the number of leaflets printed by Copier F as a percentage of the total number of leaflets printed by both copiers. Round off your answer to 2 decimal places.
Number of leaflets Copier F prints per min = 90 ÷ 3 = 30
Number of leaflets Copier G prints per min = 120 ÷ 4 = 30

From 4 p.m. to 6 p.m. = 2 h
1 h = 60 min
2 h = 120 min

Number of leaflets printed by Copier G in 4 h
= 120 x 30
= 3600

Number of leaflets printed by Copier F in 4 h
= 8733 - 3600
= 5133

Percentage of the number of leaflets that Copier F printed over the total number of leaflets printed
= ⁵¹³³₈₇₃₃ x 100%
≈ 58.78%

Answer(s): 58.78%
