Since, M alone can complete a work in 50 days.
M's one day work = 1/50
As N alone can complete the same work in 100 days.
So, N's one day work = 1/100
When they work together, we have
Work they can complete in 1 day = 1/50 + 1/100 = 3/100
Amount of work they can complete in 25 days = 25 x  3/100 = 3/4
Percentage of work they can complete in 25 days = 100 x 3/4 = 75%
