Copier V prints at a rate of 108 leaflets in every 2 minutes and Copier W prints at a rate of 124 leaflets in every 4 minutes. At 5 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 7 p.m., the total number of leaflets printed during the past two hours was 7480. Express the number of leaflets printed by Copier V 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 V prints per min = 108 ÷ 2 = 54
Number of leaflets Copier W prints per min = 124 ÷ 4 = 31

From 5 p.m. to 7 p.m. = 2 h
1 h = 60 min
2 h = 120 min

Number of leaflets printed by Copier W in 5 h
= 120 x 31
= 3720

Number of leaflets printed by Copier V in 5 h
= 7480 - 3720
= 3760

Percentage of the number of leaflets that Copier V printed over the total number of leaflets printed
= ³⁷⁶⁰₇₄₈₀ x 100%
≈ 50.27%

Answer(s): 50.27%
