It would help if you would proofread your work before you post it.
There is no indication of amount of paint used.
In terms of the walls, 1 - .4 - .25 = ?

assuming you meant to say
"after painting 1/4 of the unpainted portion"
then we have2/5 painted, so 3/5 unpainted
1/4 * 3/5 = 3/20
2/5 + 3/20 = 8/20 + 3/20 = 11/20
so 9/20 remains unpainted
