Say Total income in May is T.
So Mr Lee share 0.6T and others 0.4T
Say income of Mt Lee is X.

In June:

Income of Mr Lee is 1.2X and others income is 0.4T

Hence total income is 1.2X+0.4T in June and total income is X+0.4T in May

X = 0.6T => 1.2X = 0.72T

Total income in June is 0.72T+0.4T = 1.12T
Thus share of Mr Lee (.72/1.12) * 100 = 0.64
