Copier H prints at a rate of 95 leaflets in every 5 minutes and Copier J prints at a rate of 140 leaflets in every 5 minutes. At 5 p.m., both copiers started printing. After a while, Copier H stopped printing for some time as the ink cartridges were being changed before it continued to print again. Copier J continued printing during this time. At 7 p.m., the total number of leaflets printed during the past two hours was 8209. Express the number of leaflets printed by Copier H 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 H prints per min = 95 ÷ 5 = 19
Number of leaflets Copier J prints per min = 140 ÷ 5 = 28

From 5 p.m. to 7 p.m. = 2 h
1 h = 60 min
2 h = 120 min

Number of leaflets printed by Copier J in 5 h
= 120 x 28
= 3360

Number of leaflets printed by Copier H in 5 h
= 8209 - 3360
= 4849

Percentage of the number of leaflets that Copier H printed over the total number of leaflets printed
= ⁴⁸⁴⁹₈₂₀₉ x 100%
≈ 59.07%

Answer(s): 59.07%
