Copier F prints at a rate of 110 leaflets in every 2 minutes and Copier G prints at a rate of 148 leaflets in every 4 minutes. At 1 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 3 p.m., the total number of leaflets printed during the past two hours was 7821. 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 = 110 ÷ 2 = 55
Number of leaflets Copier G prints per min = 148 ÷ 4 = 37

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

Number of leaflets printed by Copier G in 1 h
= 120 x 37
= 4440

Number of leaflets printed by Copier F in 1 h
= 7821 - 4440
= 3381

Percentage of the number of leaflets that Copier F printed over the total number of leaflets printed
= ³³⁸¹₇₈₂₁ x 100%
≈ 43.23%

Answer(s): 43.23%
