Given- 90% of runner completed the marathon.

out of which 30% are man.

To proof -  let the total number of runner be y.

the men completed the marathon be 30% of the 90%.

30% of 90% of y = 270

\frac{30}{100}×\frac{90}{100}×y = 270

now solving the above equation

we get

Thus solving the equation

y = 1000

Thus the total runners of men who completed marathon be 1000.
