If I gave you 2 beads, there will be an increase of 4 beads in the difference between our beads because I lose 2 and you gain 2.

Example:
I have 10, and you have 10.
I gave you 2 beads.
Now I have 8 and you have 12 (our difference is 4).

So if Gina has 30 more than Haina after giving 28 beads (which makes a difference of 2 x 28),

Gina originally had (30 + 2(28)) more beads than Haina, which is 86.
