Copier N prints at a rate of 84 flyers in every 3 minutes and Copier P prints at a rate of 155 flyers in every 5 minutes. At 6 p.m., both copiers started printing. After a while, Copier N stopped printing for some time as the ink cartridges were being changed before it continued to print again. Copier P continued printing during this time. At 8 p.m., the total number of flyers printed during the past two hours was 8939. Express the number of flyers printed by Copier N as a percentage of the total number of flyers printed by both copiers. Round off your answer to 2 decimal places.
Number of flyers Copier N prints per min = 84 ÷ 3 = 28
Number of flyers Copier P prints per min = 155 ÷ 5 = 31

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

Number of flyers printed by Copier P in 6 h
= 120 x 31
= 3720

Number of flyers printed by Copier N in 6 h
= 8939 - 3720
= 5219

Percentage of the number of flyers that Copier N printed over the total number of flyers printed
= ⁵²¹⁹₈₉₃₉ x 100%
≈ 58.38%

Answer(s): 58.38%
