Copier G prints at a rate of 112 leaflets in every 2 minutes and Copier H prints at a rate of 156 leaflets in every 6 minutes. At 1 p.m., both copiers started printing. After a while, Copier G stopped printing for some time as the ink cartridges were being changed before it continued to print again. Copier H continued printing during this time. At 4 p.m., the total number of leaflets printed during the past three hours was 8681. Express the number of leaflets printed by Copier G 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 G prints per min = 112 ÷ 2 = 56
Number of leaflets Copier H prints per min = 156 ÷ 6 = 26

From 1 p.m. to 4 p.m. = 3 h
1 h = 60 min
3 h = 180 min

Number of leaflets printed by Copier H in 1 h
= 180 x 26
= 4680

Number of leaflets printed by Copier G in 1 h
= 8681 - 4680
= 4001

Percentage of the number of leaflets that Copier G printed over the total number of leaflets printed
= ⁴⁰⁰¹₈₆₈₁ x 100%
≈ 46.09%

Answer(s): 46.09%
