225 notes

Step-by-step explanation:

Let the number of notes is x.

20% of notes is:

0.2x

40% of the remainder is:

40% of 0.8x, so it is 0.8x*0.4 = 0.32x

Remaining notes are:

x - 0.2x - 0.32x = 0.48x

Total of the notes:

0.2x*10 + 0.32x*5 + 0.48x*2 = 10262x + 1.6x + 0.96x = 10264.56x = 1026x = 1026/4.56x = 225
