Solution

ANSWER:-
I will give you a simple explanation which make you understand easier.
EXPLANATION :-
There were 6 A atoms on the face-centres removing face-centred atoms

along one of the axes means removal of 2 A atoms.

Now, number of A atoms per unit cell

Number of B atoms per unit cell

Hence the resultant stoichiometry is A3B4.

Hope it makes you clear.
