Red buttons Blue buttons Total
At first 370-u u 370
Used -34 0.8u
End ratio 3 1
Red buttons left = 370-b-34 = 336-u
Blue buttons left = 0.2u
(336-u) / 0.2u = 3 ( or ratio 3/1)
336-u = 0.6u
1.6u = 336 => u = 210
Red buttons in the end = 370-u-34 = 370-210-34 = 126
Blue buttons in the end = 0.2(210) = 42
Hence red buttons more than blue buttons in the end = 126-42 = 84
