Potential of the outer plates must be same after connecting the plates. The charges produced on the central plate on the two faces must be such that the electric field on the left side of the plate must be double of that on right, so that the potential drop along the two sides is equal.
Hence charge on the left side of the central plate isand that on right is.
Since facing sides have equal and opposite charges, the right side of leftmost plate has chargeand the left side of rightmost plate has charge.

Since the outer plates have equal charges and the total charge of outermost plates must be, let the charge be.
Hence

Total charge on rightmost plate is, thus, equal to
Initial chage on this plate was 0. Hence this is also the amount of charge that has flown into it.
