Hi pls help thx
Machine A, 90 mins→360u
Therefore 1min = 360u÷90 = 4u
Machine B , 120 mins→ 360u
Therefore, 1min = 360÷120 = 3u
Given, 1 min faster machine print 6 more pages.
So, 4u-3u=6,
1u = 6
Total for each machine = 360u = 360×6 = 2160 pages
Total for both machines = 2160×2 = 4320 pages.

90:120 = 3:4
3×4u = 4×3u = 12u
90×4u = 120×3u = 90×4×6 = 2160
2×2160 = 4320 (Ans)
Machine A, 90 mins→360u
Therefore 1min = 360u÷90 = 4u
Machine B , 120 mins→ 360u
Therefore, 1min = 360÷120 = 3u
Given, 1 min faster machine print 6 more pages.
So, 4u-3u=6,
1u = 6
Total for each machine = 360u = 360×6 = 2160 pages
Total for both machines = 2160×2 = 4320 pages.
