Copier V prints at a rate of 95 brochures in every 5 minutes and Copier W prints at a rate of 138 brochures in every 6 minutes. At 2 p.m., both copiers started printing. After a while, Copier V stopped printing for some time as the ink cartridges were being changed before it continued to print again. Copier W continued printing during this time. At 5 p.m., the total number of brochures printed during the past three hours was 7266. Express the number of brochures printed by Copier V 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 V prints per min = 95 ÷ 5 = 19
Number of brochures Copier W prints per min = 138 ÷ 6 = 23

From 2 p.m. to 5 p.m. = 3 h
1 h = 60 min
3 h = 180 min

Number of brochures printed by Copier W in 2 h
= 180 x 23
= 4140

Number of brochures printed by Copier V in 2 h
= 7266 - 4140
= 3126

Percentage of the number of brochures that Copier V printed over the total number of brochures printed
= ³¹²⁶₇₂₆₆ x 100%
≈ 43.02%

Answer(s): 43.02%
