Copier L prints at a rate of 88 leaflets in every 2 minutes and Copier M prints at a rate of 150 leaflets in every 5 minutes. At 7 p.m., both copiers started printing. After a while, Copier L stopped printing for some time as the ink cartridges were being changed before it continued to print again. Copier M continued printing during this time. At 9 p.m., the total number of leaflets printed during the past two hours was 8732. Express the number of leaflets printed by Copier L 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 L prints per min = 88 ÷ 2 = 44
Number of leaflets Copier M prints per min = 150 ÷ 5 = 30

From 7 p.m. to 9 p.m. = 2 h
1 h = 60 min
2 h = 120 min

Number of leaflets printed by Copier M in 7 h
= 120 x 30
= 3600

Number of leaflets printed by Copier L in 7 h
= 8732 - 3600
= 5132

Percentage of the number of leaflets that Copier L printed over the total number of leaflets printed
= ⁵¹³²₈₇₃₂ x 100%
≈ 58.77%

Answer(s): 58.77%
