Copier G prints at a rate of 92 brochures in every 2 minutes and Copier H prints at a rate of 152 brochures in every 4 minutes. At 8 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 brochures printed during the past two hours was 8923. Express the number of brochures printed by Copier G as a percentage of the total number of brochures printed by both copiers. Round off your answer to 2 decimal places.
Number of brochures Copier G prints per min = 92 ÷ 2 = 46
Number of brochures Copier H prints per min = 152 ÷ 4 = 38

From 8 p.m. to 10 p.m. = 2 h
1 h = 60 min
2 h = 120 min

Number of brochures printed by Copier H in 8 h
= 120 x 38
= 4560

Number of brochures printed by Copier G in 8 h
= 8923 - 4560
= 4363

Percentage of the number of brochures that Copier G printed over the total number of brochures printed
= ⁴³⁶³₈₉₂₃ x 100%
≈ 48.90%

Answer(s): 48.90%
