#include<stdio.h>

int main()
{
float m,n;
int p;
scanf("%d %f",&p,&n);
m=n;
n=n-p;
n=n-0.50;
if(n>50&&p<120&&p%5==0)
{
printf("%.02f",n);
}
else
printf("%.02f",m);
return 0;
}

Well you have messed up with your code . Who gave that n>50 and p<120 . In codechef , you will cin values and get input and use those p=120 was just an example you cant assume anything .
I am giving a sample code to you for the problem , any problem contact me

Firstly correct the format of output statement the specifier should be .2f and not .02f.
Next the condition should be if((p%5==0)&&(n-p-0.5>0))
You should write input statements separately for each input. It has also landed me in trouble many times. If this still gives wrong answer, try inserting “printf(”\n");" at the end of last output statement. Hope this helps…

Your code gives wrong answer for input 400 700.05

Answer should be 299.55 but your code gives 700.05

Corrected Code:

#include<stdio.h>
int main()
{
float m,n;
int p;
scanf("%d %f",&p,&n);
m=n;
//n=n-p;  //this condition is  not required here it is needed later
n=n-0.5;
//if(n>50&&p<120&&p%5==0)	//wrong bound checking, why are you checking for 120 and 50 ?? !!
if((p%5==0)&&(p<=n))
{
    n=n-p;
printf("%.2f",n);   //change here  from .02 to .2
}
else
printf("%.2f",m); //change here from .02 to .2
return(0);
}
