Copier K prints at a rate of 96 leaflets in every 3 minutes and Copier L prints at a rate of 132 leaflets in every 6 minutes. At 2 p.m., both copiers started printing. After a while, Copier K stopped printing for some time as the ink cartridges were being changed before it continued to print again. Copier L continued printing during this time. At 5 p.m., the total number of leaflets printed during the past three hours was 8276. Express the number of leaflets printed by Copier K 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 K prints per min = 96 ÷ 3 = 32
Number of leaflets Copier L prints per min = 132 ÷ 6 = 22

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

Number of leaflets printed by Copier L in 2 h
= 180 x 22
= 3960

Number of leaflets printed by Copier K in 2 h
= 8276 - 3960
= 4316

Percentage of the number of leaflets that Copier K printed over the total number of leaflets printed
= ⁴³¹⁶₈₂₇₆ x 100%
≈ 52.15%

Answer(s): 52.15%
