Copier G prints at a rate of 84 leaflets in every 3 minutes and Copier H prints at a rate of 120 leaflets in every 6 minutes. At 6 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 10 p.m., the total number of leaflets printed during the past four hours was 7854. 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 = 84 ÷ 3 = 28
Number of leaflets Copier H prints per min = 120 ÷ 6 = 20

From 6 p.m. to 10 p.m. = 4 h
1 h = 60 min
4 h = 240 min

Number of leaflets printed by Copier H in 6 h
= 240 x 20
= 4800

Number of leaflets printed by Copier G in 6 h
= 7854 - 4800
= 3054

Percentage of the number of leaflets that Copier G printed over the total number of leaflets printed
= ³⁰⁵⁴₇₈₅₄ x 100%
≈ 38.88%

Answer(s): 38.88%
