In a marathon 90% runner were managed to complete it and 30% were men if 270 men completed it how many total runner began the marathon

1000 runners

Step-by-step explanation:

Take total number of runners to be x

90% of x managed to complete the marathon= 90/100 × x =0.9x

30% of those who completed the marathon were men= 30% × 0.9x

=0.3×0.9x= 0.27x

=270 men completed the marathon; this means

0.27x=270find x by dividing both sides by 0.27

x= 270/0.27

x=1000 runners

1000

Step-by-step explanation:

Given : In a marathon 90% runner were managed to complete it and 30% were men.

To Find: If 270 men completed it how many total runner began the marathon.

Solution:

Let x be the number of total runners

Now we are given that 90% runner were managed to complete it

So, number of runners managed to complete =

Now we are given that out of 90% , 30% were men

So, Numbers of men runners =

Now we are given that 270 men completed it

So,

[tex]x=1000/tex]

Hence 1000 runners began the marathon.

step-by-step explanation:

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
