Given :
Number of moles of Nitrogen(N2) = 1mole
Number of moles of Hydrogen (H2) = 3moles  
So total number of moles =1+3= 4moles 
Total pressure = 3 atm. 
Now,  
        Mole fraction of N2=( number of moles of N2)/(total no of moles) 
So, 
Mole fraction of N2=1/4=0.25
 Now, 
        Partial pressure of N2=(mole fraction of N2)*(total pressure) 
On putting values we get
Partial pressure of N2=( 0.25) * (3) =0.75 atm
