Total men days = 40 *40 = 1600 men-days.
40 men work for 10 days = 400 men days
35men work for 10 days = 350 men days
30 men work for 10 days = 300 men days.
25 men work for 10 days = 250 men days
20 men work for 10 men days = 200 men days.
Total men days till now = 400 +350 +300 +250 +200 = 1500 men days.
Rest men days = 1600 - 1500 = 100 men days.
Now 15 men will work for complete 100 men days in = 100/15 = 6.66 days.
So total days = 10*5 + 6.66 = 56.66 days.
