Answer 2

let total no.of runners be x

let total no.of runners completed = 90/100* x

so,

90/100*x

completed men= 30/100*y ( y is 90/100)

then,

= 9

0x/100 X 30/100

= 27x/100 = 270

no. of men completed is already given in numbers thats how 270 came there....

now,

= 27x = 270 X 100

= x = 270 X 100/27

= 1000.

therefore total no.of runners are 1000
