Dear student
Please find the solution to the asked query:

The question is tricky However, in my opinion:
A cubic void is present at the centre of the unit cell and atom at
in a cubic void will have a coordination number of 8
So 4th coordination number and 3rd coordination number will have
ratio : 4/8 :3/8 , i e 4:3

Hope this information will clear your doubts regarding the topic If
