Answer: 1000

Step-by-step explanation: Let no. of total runner who began be X.

90% runners managed to complete.

=> 0.9*X completed the Marathon

30% of them were men.

=> 30% of (0.9*X) were men

=> 0.3*0.9*X people were men.

Given, 270 men completed.

Thus, 0.3*0.9*X = 270

=> X = 270/(0.3*0.9)

X = 1000

Answer: Total no. of people who take part in the marathon are 900

Step-by-step explanation:

Let the no. of people who take part in the marathon be x

Now, A.T.Q

x/100*30 = 270

x = 900

Thus 900 people take part in the marathon

And 900/100*90 = 810

Thus 810 people managed to complete the marathon
