90% completed it.
30% are men.
Let the total men be x.
30x/100=270
=x=270*100/30
=x=900
So there were 900 men who started the marathon.
Hope it helps.

Total percentage of runners that complete the marathon
= 90%
Total percentage of male runners that complete the marathon
= 30% of 90%
= 0.3 x 90
= 27%
Total percentage of male runners that complete the marathons= 27%
Total male runners that complete the marathons= 270
27% = 270
1% = 270 ÷ 27 = 10
1% = 10 runners
100% = 10 x 100 = 1000 runners
Answer: There are 1000 runners in the marathon.
