Question

83% 90% of runners who started a marathon completed it. Of those, 30% are men. If 270 men completed the marathon, then how many total runners started the marathon?

Answer 1

I didn't find the beginning of the question typed correctly. Still trying it.

Let's assume the total no of people taking part as x

30%of x= 270

30/100 X x=270

Solving this eqn we get the ans

X= 900

Answer 2

Answer:

1000 runners started the marathon

Step-by-step explanation:

Let the total number who began the race be x.

Those who completed the race were 90% of x which is = 0.90x × 0.30 = 0.27x

The number of men who completed the race are 270 men.

From the workings above we have the number of men who completed the race.

0.27x = 270

x = 270/0.27

x = 1000

Therefore the number of people who began the race were 1000 both women and men.
