Let assume C's efficiency=100
Then B's efficiency=100+60%of100=160
Then A's efficiency=160+80%of160=288

Ratio of efficiency_____
A:B:C
72:40:25

Then ratio of time______
A:B:C
1/72:1/40:1/25=25:45:72

A takes 20 days less than B (according to time ratio)
A takes 40 days less than B (given in question)
So
A can complete the work in=25×40/20=50 days
B can complete the work in=45×40/20=90 days
C can complete the work in=72×40/20=144 days
Let assume total work is 1
A's work+B's work+C's work=1
25/50 + 30/90 + C/144=1
1/2 + 1/3 + C/144=1
C=24 days ans.
