Copier T prints at a rate of 108 leaflets in every 2 minutes and Copier U prints at a rate of 135 leaflets in every 3 minutes. At 2 p.m., both copiers started printing. After a while, Copier T stopped printing for some time as the ink cartridges were being changed before it continued to print again. Copier U continued printing during this time. At 4 p.m., the total number of leaflets printed during the past two hours was 8012. Express the number of leaflets printed by Copier T 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 T prints per min = 108 ÷ 2 = 54
Number of leaflets Copier U prints per min = 135 ÷ 3 = 45

From 2 p.m. to 4 p.m. = 2 h
1 h = 60 min
2 h = 120 min

Number of leaflets printed by Copier U in 2 h
= 120 x 45
= 5400

Number of leaflets printed by Copier T in 2 h
= 8012 - 5400
= 2612

Percentage of the number of leaflets that Copier T printed over the total number of leaflets printed
= ²⁶¹²₈₀₁₂ x 100%
≈ 32.60%

Answer(s): 32.60%
