Copier M prints at a rate of 110 leaflets in every 2 minutes and Copier N prints at a rate of 130 leaflets in every 5 minutes. At 8 p.m., both copiers started printing. After a while, Copier M stopped printing for some time as the ink cartridges were being changed before it continued to print again. Copier N continued printing during this time. At 10 p.m., the total number of leaflets printed during the past two hours was 8748. Express the number of leaflets printed by Copier M 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 M prints per min = 110 ÷ 2 = 55
Number of leaflets Copier N prints per min = 130 ÷ 5 = 26

From 8 p.m. to 10 p.m. = 2 h
1 h = 60 min
2 h = 120 min

Number of leaflets printed by Copier N in 8 h
= 120 x 26
= 3120

Number of leaflets printed by Copier M in 8 h
= 8748 - 3120
= 5628

Percentage of the number of leaflets that Copier M printed over the total number of leaflets printed
= ⁵⁶²⁸₈₇₄₈ x 100%
≈ 64.33%

Answer(s): 64.33%
