Copier W prints at a rate of 106 leaflets in every 2 minutes and Copier X prints at a rate of 132 leaflets in every 4 minutes. At 6 p.m., both copiers started printing. After a while, Copier W stopped printing for some time as the ink cartridges were being changed before it continued to print again. Copier X continued printing during this time. At 8 p.m., the total number of leaflets printed during the past two hours was 7692. Express the number of leaflets printed by Copier W 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 W prints per min = 106 ÷ 2 = 53
Number of leaflets Copier X prints per min = 132 ÷ 4 = 33

From 6 p.m. to 8 p.m. = 2 h
1 h = 60 min
2 h = 120 min

Number of leaflets printed by Copier X in 6 h
= 120 x 33
= 3960

Number of leaflets printed by Copier W in 6 h
= 7692 - 3960
= 3732

Percentage of the number of leaflets that Copier W printed over the total number of leaflets printed
= ³⁷³²₇₆₉₂ x 100%
≈ 48.52%

Answer(s): 48.52%
